Important information for proposers

All proposals must be submitted in accordance with the requirements specified in this funding opportunity and in the NSF Proposal & Award Policies & Procedures Guide (PAPPG) that is in effect for the relevant due date to which the proposal is being submitted. It is the responsibility of the proposer to ensure that the proposal meets these requirements. Submitting a proposal prior to a specified deadline does not negate this requirement.

Dear Colleague Letter

Availability of Earth Observation Data for NSF-Funded Researchers

Alerts NSF funded researchers to the existence of high-quality Earth observation data through the National Aeronautics and Space Administration (NASA) Commercial SmallSat Data Acquisition (CSDA) Program at no additional cost.

Dear Colleagues:

Recent developments in satellite and sensor technology have led to unprecedented advances in the resolution, extent, and frequency of Earth observations. High spatial and temporal resolution capabilities now allow for the investigation of crucial research questions across several Earth system science education and research themes. Yet, many of these datasets have previously been unavailable for research purposes because they are generated by commercial providers. This Dear Colleague Letter (DCL) announces the availability of high-quality commercial Earth observation data to NSF-funded researchers at no additional cost through the National Aeronautics and Space Administration (NASA) Commercial SmallSat Data Acquisition (CSDA) Program.

To inform and assist interested researchers, this DCL describes the process for gaining access to this imagery, the currently available datasets, and related training resources.


Through the CSDA Program, all NSF-funded researchers have access to a vast array of datasets. An overview of the CSDA program can be found here:

To request access, please fill out the form located at: You will need to include your active NSF grant number on the form (a seven-digit number), the contact information for the managing NSF Program Officer for the award, and a description of how the requested remote sensing data would be used to support your NSF-funded project. Access must be requested by an individual user associated with an NSF-funded project. The applications are then reviewed by NASA to determine eligibility, which will take about 2–3 weeks. Once verified, the user will be provided additional information on how to request and access data. There is a 30-day latency on PlanetScope access; for no-latency access on time-sensitive projects (i.e., ongoing natural disasters), waivers can be requested.

NSF researchers funded by the Office of Polar Programs also have access to high resolution satellite imagery from Maxar and other geospatial services at no additional cost to their award. Please see the Polar Geospatial Center webpage for more details:


Several very high-resolution remote sensing data sets are available for use, with the potential to power many scientific advances. Currently, data from Spire Global Subsidiary, Inc., and data acquired through NASA's Earth Science Division’s collaboration with the International Space Station (ISS) from the Teledyne Brown Engineering, Inc. DLR Earth Sensing Imaging Spectrometer (DESIS) are available for all U.S. Government-funded researchers. Data from Planet, covered under the CSDA program, are also available for U.S. Government Federal civil agencies and NSF-funded researchers. NSF-funded researchers are included in the category of U.S. Government (funded) researchers.

Information about these vendors, user licenses, and data is available on the Commercial Datasets page: Information on the available satellites, their orbits, and their sensors' temporal and spectral resolutions is also available at that webpage. As additional commercial small satellite datasets are evaluated and acquired, those datasets will also be made available.

There are a variety of training resources for the science and education community to help researchers get started with the data, access pathways, and integration with other software packages. The CSDA Program conducts a variety of conferences and Lunch and Learn sessions that are available here:
