Arctic Snow Depth on Sea Ice - Data Format - HiMAC Data Portal

Data Format Northern Hemisphere Snow depth files from SMMR and SSM/I (1978-)

Data processed with a five day history. This allows some determination of variability in the snowcover due to weather events or melt events, which gets flagged in the dataset.

Files are stored in directories per winter season (WSYYYY_YYYYdata), starting 1 October and ending 30 September the following year. Files are named ssmi_n_snowdepth_5day_YYYYDDD.img, where YYYY is the year and DDD is the day-of-year. Files may be gzipped.

Int arrays, 304 x 448, Little-endian (unix will need to byteswap)

Values are:

0-100 snow depth in cm 110 missing 120 land 130 open water 140 multi-year ice (no snow calculations done) 150 variability flag (significant changes in the snow depth over the period covered) as a result of weather effects and short-term melt events. 160 summer melt (5 consecutive variable days after April 1; will be flagged melt until 1 October)
