COVERAGE OF ICE SHEET: SWG‐PSTG RECOMMENDATIONS To acquire a set (about 90) of sites and glaciers (also called supersites) with high‐resolution X‐band sensors,
on the base of the priority level identified by the scientific community in Greenland and Antartic (3 levels). To perform the coverage of the Antarctic coastApproach, General recommendations Polarization HH Stripmap acquisition mode (Time series)with a incidence angle range 25 and 45 degrees (even 57 to cover South Pole).

BACKGROUND MISSION
Started in May 2011
The background mission applies a systematic low priority acquisition strategy, so to obtain regular, repetitive and comparable acquisitions and to minimize possible conflicts with existing user requests.
Create an archive of images also dedicatedto interferometric applications.
Maximize the system exploitation duringthe operation lifetime of the constellation.

Task Group
ASI contribution to PSTG.
ObjectiveTo meet the objectives of the Polar Space Task Group (PSTG)and assuring the data continuity through space-borne datacollection over ice sheets, from September 2014 newbackground acquisition plans have been implemented on polarareas. to minimize conflicts to continue time series that could be already present in
the archive.
Approach: Acquisition geometries of plans chosen in order
Stripmap mode (3-5 m res., 40 km swath), HH, asc/ desc directions, right look side, incidence angles between 25° - 45°, Time resolution of 4 or 8 dais ( glaciers lev3, higher
proirity), 16 days (glaciers lev 2 and 1, antartic coast) ScanSAR wide region mode (30 m resolution, 100 km
swath) ScanSAR huge region mode (100 m resolution, 200 km
swath)

Selected projects are supported for a maximum of twoyears, through a provision of a maximum of 100 free ofcharge COSMO‐SkyMed scenes from both archive new acquisitions
Topics: Mainly addressed to monitoring of infrastructures and building stock surveying of archaeological heritage in cooperation with
institutions developing of new tools and SAR methods.
An Open Call for national SME’s community waspublished on the ASI website to promote theexploitation of COSMO‐SkyMed data and theimprovement of existing applications or thedevelopment of new technologies and algorithmsbased on EO information and to stimulate the wholeof the Italy’s industrial fabric (SMEs), which isstrategic for the Country.

FOCUS ON POLAR AREAS STUDIESThe studies, on‐going or concluded, conducted in the framework ofagreements or projects activated with ASI by several Institutional users
Distribution per thematic area of institutional projects on polar studies based on COSMO‐SkyMed data exploitation (2013‐2015)
Over the three‐year period 2013‐2015, 240 projects have been activated,the 8% of them regards studies of polar areas.
The majority have been activated in the framework of ASI‐CSA JOINT AO, due to a strong interest in this topic from the Canadian reserachers (22% of 48 projects). The interest on these area is continuing in the framework of CURRENT CSK OPEN CALL ( publicated on 25 February 2015 and PERMANENTLY OPEN
The users have required mostly STRIPMAP HIMAGE over all thematic areas to carryout interferometric studies. The SPOTLIGHT sensor mode have been requiredmainly for permafrost studies, instead SCANSARWIDE for glaciers monitoring.
