PIOMAS Data

PIOMAS Ice Volume Data, 1979-present

Daily: Click to Download Daily Ice Volume Data (gzipped tar file)

Format:

Data are in “gz” compressed format and need to be uncompressed.  They are presented in a simple ASCII formatted  table with 3 columns:  Year,  Day of Year, Volume. Leap years in PIOMAS are treated by integrating forward for 365 days. For leap years this means that no integration is performed for the last day of the year. The data presented here show the first 365 days of the year. Volume is given in 103 km3

Monthly: Click to Download Monthly Ice Volume Data (text file)

Format:

Data are in ASCII table format with columns for each month and rows for years 1979 through present. Volume is given in 103 km3. Missing values are coded as -1.

Format:

Data are in “gz” compressed format and need to be uncompressed.  They are presented in a simple ASCII formatted  table with 3 columns:  Year,  Day of Year, Thickness. Leap years in PIOMAS are treated by integrating forward for 365 days. For leap years this means that no integration is performed for the last day of the year. The data presented here show the first 365 days of the year. Thickness is given in m. Note that the file provides average thickness over the PIOMAS domain for areas thicker than 0.15 m
