Project Proposal (Restrained): Access to this data collection is provided only after submitting and receiving approval for a project proposal. Access is limited to accepted projects that meet the conditions defined by ESA.

Access Steps:

1. Create or log in to EO Sign In (users are recommended to register with an institutional email address).
2. Go to the Project Proposal form.
3. Complete and submit the form with details of your proposed data use. 
4. ESA will evaluate your proposal (normally within 4–6 weeks). 
5. Go to the EO User Portal to check the status of your request
6. The proposal will be evaluated by ESA, which normally takes between 4 and 6 weeks
7. If approved, you will receive a confirmation email with the quota assigned and instructions on how to order the data. 

The collection is open for research and application development projects, exclusively for non-commercial, non-operational, and civil Earth observation research purposes. Submission of a Project Proposal is mandatory and subject to evaluation by ESA and the data owner. 

ESA supports as many high-quality and innovative projects as possible within the quota limits. This means only a limited number of products can be allocated to each project. 

• Learn more about the quota limit and see a comparison with other missions in our FAQ: How much data may I request in a Project Proposal?
• Browse and download data via ESA’s Third Party Missions (TPM) dissemination service and catalogue, which supports both treeview navigation and interactive map search.
• Discover COSMO-SkyMed products through ESA’s Exploring Earth service, which enables browsing and downloading across multiple ESA and Third Party Mission datasets using spatial and temporal filters.
• For guidance on preparing your proposal, see our How to access data requiring a project proposal guide.

The COSMO-SkyMed archive collection consists of COSMO-SkyMed products requested by ESA supported projects over their areas of interest around the world. The dataset regularly grows as ESA collects new products over the years.

The following list delineates the characteristics of the SAR measurement modes that are disseminated under ESA Third Party Missions (TPM).

• STRIPMAP HIMAGE (HIM): Achieving medium resolution (3 m x 3 m single look), wide swath imaging (swath extension ≥40 km).
• STRIPMAP PINGPONG (SPP): Achieving medium resolution (15 m), medium swath imaging (swath ≥30 km) with two radar polarization's selectable among HH, HV, VH and VV.
• SCANSAR WIDE (SCW): Achieving radar imaging with swath extension of 100 x 100 km2 and a spatial resolution of 30 x 30 m2.
• SCANSAR HUGE (SCH): Achieving radar imaging with swath extension of 200 x 200 km2 and a spatial resolution selectable of 100 x 100 m2.

Processing Levels:

• Level 1A (L1A) - Single-look Complex Slant - (SCSB and SCSU): RAW data focused in slant range-azimuth projection, that is the sensor natural acquisition projection; product contains In-Phase and Quadrature of the focused data, weighted and radiometrically equalised.The processing of the 1A_SCSU product differs from that of the 1A_SCSB product for the following features:a non-weighted processing is performed, which means that windowing isn't applied on the processed bandwidth; radiometric equalisation (in terms of compensation of the range antenna pattern and incidence angle) is not performed; hence only compensation of the antenna transmitter gain and receiver attenuation and range spreading loss is applied.
• Level 1B (L1B)- Detected Ground Multi-look (DGM): Product obtained detecting, multi-looking and projecting the Single-look Complex Slant data onto a grid regular in ground. Spotlight Mode products are not multi-looked.
• Level 1C (L1C)- Geocoded Ellipsoid Corrected (GEC) and Level 1D (L1D)- Geocoded Terrain Corrected (GTC): Obtained projecting the L1A product onto a regular grid in a chosen cartographic reference system. In case of Lev 1C the surface is the earth ellipsoid while for the L1D a DEM (Digital Elevation Model) is used to approximate the real earth surface.

Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service.

As per ESA policy, very high-resolution data over conflict areas cannot be provided.
