[Data description] Monthly total freeboard (Ft) and snow depth (hs) data for January-February-March 2003-2020 period produced by Lee and Shi al. (2021, manuscript in preparation) are provided. Both variables are derived from satellite passive measurements; Total freeboard was obtained from AMSR measurements and snow depth was obtained from AMSR and AVHRR measurements. The uploaded file titled "monthly averaged total freeboard and snow depth (JFM 2003-2020).zip", contains two folders for the each variable and corresponding monthly maps are included. Naming convention is "variable_yyyymm.bin" and data format is 32 bit floating point array in shape of 448 x 304 (25 km polar stereographic grid). Here we provide example Python code to read monthly snow depth of January 2003 using Numpy. hs = np.fromfile('hs_200301.bin', dtype=np.float32).reshape(448,304) Geocoordinate tools for the 25 km polar stereographic grid are available at NSIDC website (https://nsidc.org/data/polar-stereo/tools_geo_pixel.html) [Abbreviations] AMSR: Advanced Microwave Scanning Radiometer AVHRR: Advanced Very High Resolution Radiometer NSIDC: National Snow and Ice Data Center
