Introduction: Small Changes That Could Shape Major Atmospheric Discoveries
Earth’s atmosphere is a living, interconnected system—constantly moving energy, moisture, particles, and chemical compounds across continents and oceans. Understanding that system requires more than satellites and ground stations. It also depends on airborne research campaigns capable of collecting detailed measurements directly within the atmosphere, where many of the processes influencing weather, climate, air quality, and environmental change unfold.
NASA’s Earth Science Division has recently released ROSES-25 A.14 Atmosphere, inviting researchers to submit proposals focused on the analysis and modeling of data collected through NASA-supported airborne campaigns. The opportunity is designed to encourage scientists to extract new knowledge from valuable atmospheric datasets and develop improved models that can help explain how Earth’s atmosphere behaves.
On or around July 30, 2026, NASA issued several corrections and updates to the A.14 Atmosphere announcement. While the changes may appear administrative, they are important for researchers preparing proposals. The revisions clarify which sections applicants should follow, formally address the use of generative artificial intelligence, and add a required annual rough-budget estimate to the proposal information submitted through NASA’s NSPIRES system.
These updates reinforce an important principle in scientific funding: clear instructions and transparent expectations are essential for producing strong, credible, and competitive research proposals.
Original Summary: What NASA Changed
NASA’s Earth Science Division released A.14 Atmosphere as part of the ROSES-25 program to solicit proposals involving the analysis and modeling of data from NASA-supported airborne atmospheric campaigns.
Several corrections were later made to the opportunity. An incorrect reference in Section 4.1 was corrected so that it now directs applicants to Section 4.2, which contains information related to the relevant sub-element.
NASA also added a new section, Section 4.3.3, “Use of Generative AI,” providing guidance related to the role of generative artificial intelligence in proposal preparation or related activities.
In addition, the NSPIRES cover page was updated. The NOI Program Specific Data Cover Page Element now requires applicants to provide a rough estimate of the budget needed per year.
NASA indicated that newly added language appears in bold, while deleted material is shown with strikethrough formatting, making the revisions easier for applicants to identify.
Questions regarding A.14 Atmosphere may be directed to Ken Jucks, Emma Knowland, and the other points of contact identified in Section 4 of the official announcement.
The Importance of NASA’s Atmospheric Airborne Campaigns
NASA’s airborne science missions occupy a critical position between satellite observations and measurements collected at the Earth’s surface. Satellites can observe enormous regions, while ground-based instruments can provide detailed information at specific locations. Aircraft-based campaigns help bridge those perspectives by collecting measurements from within the atmosphere itself.
Research aircraft can carry advanced instruments designed to study clouds, aerosols, greenhouse gases, atmospheric chemistry, radiation, storms, and other environmental processes. These observations can reveal information that may be difficult to obtain from space or from the ground alone.
Airborne campaigns are especially valuable when scientists need high-resolution measurements across multiple altitudes. Atmospheric conditions can change dramatically between the surface and the upper atmosphere, and understanding those vertical differences is essential for improving scientific models.
The data collected during these missions may continue to generate scientific value long after the aircraft have landed. Researchers can revisit archived datasets, combine them with newer observations, apply improved analytical methods, and discover patterns that were not visible when the data was first collected.
Why Data Analysis and Modeling Matter
Collecting atmospheric observations is only the beginning of the scientific process. Raw measurements must be calibrated, validated, interpreted, and incorporated into models before they can support broader conclusions.
The A.14 Atmosphere opportunity emphasizes the importance of transforming existing campaign data into new scientific knowledge. Researchers may use these datasets to investigate atmospheric processes, evaluate model performance, improve simulations, or explore relationships between different environmental variables.
Atmospheric models are essential tools for understanding complex systems. They can help scientists examine how aerosols influence clouds, how atmospheric chemistry changes over time, how energy moves through the climate system, and how regional processes connect to global conditions.
Improved models may also support better projections of future environmental behavior. However, model development depends on reliable observations. Airborne campaign data can provide detailed evidence that helps researchers test whether simulations accurately represent real atmospheric conditions.
A Correction That Prevents Proposal Confusion
One of the July 30 corrections involved an erroneous reference in Section 4.1. The document was updated so that applicants are directed to Section 4.2 regarding the relevant sub-element.
A reference error may seem minor, but proposal documents often contain detailed requirements spread across multiple sections. If an applicant follows the wrong reference, they may misunderstand eligibility rules, submission requirements, or the scientific scope of the opportunity.
Correcting the reference reduces unnecessary ambiguity and helps ensure that researchers evaluate their proposals against the appropriate criteria.
For applicants working under deadlines, clarity can be just as important as scientific quality. A well-designed research project may still face difficulties if the proposal does not follow the required instructions.
Generative AI Enters the Proposal Framework
The addition of Section 4.3.3, “Use of Generative AI,” is one of the most notable changes in the updated announcement.
Generative AI is increasingly being used across scientific research. Researchers may use AI tools to assist with literature exploration, programming, data processing, technical writing, visualization, and the development of analytical workflows.
At the same time, AI-generated material can introduce important concerns. These include inaccurate information, fabricated references, unclear authorship, data confidentiality risks, and uncertainty regarding the reliability of generated scientific explanations.
By adding a dedicated section, NASA is signaling that generative AI is now relevant enough to require explicit guidance within the proposal process.
The update does not mean that AI replaces scientific judgment. Researchers remain responsible for the accuracy, originality, integrity, and technical quality of their work.
Responsible AI Use in Earth Science
AI can accelerate scientific work, but it must be used carefully. Atmospheric research often involves complex datasets, specialized instruments, and highly technical models. An AI-generated explanation may sound convincing while containing incorrect assumptions or unsupported conclusions.
Researchers should independently verify AI-generated code, equations, citations, and scientific interpretations. AI tools can assist with productivity, but they should not become an unquestioned source of scientific truth.
For example, an AI system might help create an initial script for processing atmospheric measurements. The researcher must still confirm that the code handles missing values correctly, applies the appropriate units, preserves metadata, and does not introduce errors into the analysis.
Scientific accountability remains human. The researcher submitting the proposal is responsible for the final work, regardless of which software tools were used during preparation.
The New Annual Budget Requirement
NASA also updated the NSPIRES cover page to include a required rough budget estimate per year under the NOI Program Specific Data Cover Page Element.
Budget information helps funding organizations understand the expected scale of proposed work. A multi-year research project may involve personnel, computing resources, data storage, model development, travel, instrument support, and other operational needs.
An annual estimate can provide a clearer view of how resources may be distributed across the lifetime of a project.
For applicants, the new requirement means that financial planning should begin early. A proposal should not treat the budget as an isolated administrative task. The requested resources should align with the scientific objectives, project schedule, staffing plan, and expected research outputs.
A strong budget tells a coherent story: the scientific goals explain the work, the work explains the resources, and the resources support the expected results.
Transparency Through Bold and Strikethrough Text
NASA noted that new language in the updated document appears in bold, while deleted language is displayed using strikethrough formatting.
This approach makes the revision process more transparent. Applicants can quickly identify what changed without comparing every sentence against an earlier version.
Visible revision tracking is particularly useful when updates occur after researchers have already begun preparing proposals. It allows teams to review only the affected sections and adjust their work efficiently.
The practice also reduces the risk that applicants will rely on outdated requirements.
Deep Analysis: Building a Reliable Atmospheric Data Workflow
Data Preparation: Protect the Scientific Foundation
Atmospheric datasets may contain missing values, inconsistent timestamps, instrument-specific formats, calibration information, and measurements recorded at different altitudes or sampling intervals.
Before modeling begins, researchers should inspect the data and preserve the original files.
mkdir -p nasa_atmosphere/{raw_data,processed_data,models,figures,logs}
cd nasa_atmosphere
A structured project directory helps separate original observations from processed outputs.
File Integrity: Verify the Original Data
Researchers should calculate checksums before modifying downloaded files.
sha256sum raw_data/ > logs/raw_data_checksums.txt
This creates a record that can help confirm whether the original data changed unexpectedly.
Metadata Review: Understand What Each Variable Means
Scientific analysis should begin with metadata rather than assumptions.
import xarray as xr
dataset = xr.open_dataset("raw_data/atmosphere_campaign.nc")
print(dataset) print(dataset.variables) print(dataset.attrs)
Researchers should confirm units, coordinate systems, timestamps, altitude definitions, instrument calibration details, and quality-control flags.
Data Quality: Identify Missing or Invalid Measurements
A basic quality review may reveal gaps or unexpected values.
for variable in dataset.data_vars:
missing = dataset[variable].isnull().sum().item()
print(f"{variable}: {missing} missing values")
Missing observations should not automatically be replaced. The correct treatment depends on the scientific purpose and the nature of the measurement.
Reproducibility: Record the Software Environment
Research teams should document the software versions used during analysis.
python --version pip freeze > logs/requirements.txt
Reproducibility is especially important when results may be reviewed, extended, or compared years after the original analysis.
Version Control: Track Analytical Changes
Git can help researchers record modifications to code and documentation.
git init
git add .
git commit -m "Initialize atmospheric campaign analysis workflow"
Each major analytical change should be documented clearly.
Model Validation: Compare Predictions With Observations
A model should be evaluated using independent or appropriately separated observations.
from sklearn.metrics import mean_absolute_error, mean_squared_error
mae = mean_absolute_error(observed, predicted) rmse = mean_squared_error(observed, predicted) 0.5
print("MAE:", mae)
print("RMSE:", rmse)
A low error value does not automatically prove that a model is scientifically valid. Researchers must also examine whether the model captures meaningful atmospheric behavior.
AI-Assisted Analysis: Verify Every Output
Generative AI may help produce code, but generated scripts should be reviewed before being used on scientific data.
python -m pytest tests/
Automated tests can help identify unexpected behavior, but they do not replace expert scientific review.
Documentation: Preserve the Research Story
A complete workflow should explain how raw observations became scientific conclusions.
cat > README.md <<'EOF' NASA A.14 Atmosphere Analysis
This project documents data preparation, quality control,
model development, validation, and reproducibility steps.
EOF
Clear documentation can make a project easier to review, reproduce, and expand.
