AARI 10-Day Arctic Ocean EASE-Grid Sea Ice Observations

Entry ID: NSIDC-0050

[ Update this Record ]

Summary

Abstract: NOTE: This data set has been replaced by the Sea Ice Charts of the Russian Arctic in Gridded Format, 1933-2006 data set (http://nsidc.org/data/g02176.html). These gridded ice charts represent a reformatting of information contained in another data set, the Russian Arctic and Antarctic Research Institute's (AARI) 10 Day Digital Arctic Sea Ice Charts. AARI digitized Arctic sea ice concentration ...

Quality It is impossible to assess errors that might have occurred in translating ice observations to the original operational charts and to SIGRID files, since these steps were performed at AARI. However, AARI estimates that ice edge boundaries are generally accurate to between 2 and 10 km under typical ice reconnaissance conditions, and to within 50 km under the worst conditions. Quality control routines assessed the 'correctness' of the AARI coding (i.e., checked whether the AARI implementation of SIGRID matched the published standard). Few errors were found in AARI's coding of the files.
