Release Note

The 4th snow_cci Climate Research Data Packages (CRDP) including Snow Cover Fraction (SCF) time series from MODIS and AVHRR sensors and Snow Water Equivalent (SWE) time series from SMMR, SSM/I and SSMI/S instruments and the 1st SCF CRDP from SLSTR sensor have been released in Q3/Q4 2025.

Daily SCF products are available with 0.01° (about 1 km) pixel spacing from Terra MODIS data for the period 24/02/2000 – 31/12/2023, and from Sentinel-3 SLSTR data for the period 01/09/2020 – 31/12/2022, and with 0.05° (about 5 km) pixel spacing from AVHRR data for the period 01/01/1979 – 31/12/2023.

In forested areas, the SCF CRDPs provide two different thematic information: snow viewable on top of the forest canopy (SCFV), and snow on the ground (SCFG), i.e., a canopy correction was applied. In non-forested areas, the SCFV and the SCFG products are equal.

Daily SWE products are available with 0.10° (about 10 km) pixel spacing for the winter periods 1979 - 2023. SWE products provide the snow mass information for the Northern Hemispheric land areas, but the geographic extent of the products is global.

Data Access

The snow_cci products are available via the Open Data Portal.
