Abstract Fix for incorrect labeling of snow/ice covered lake as land.
Problem Statement Snow/ice covered lakes in the MOD10A2 product are erroneously mapped as land. This problem exists in the V004 and V005 code and is caused by a variable name error in the code.
Description of Change Correct the variable name in one line of code in MOD_PR10A2.ProcessDailySnowDay.c.
Products Affected L3 8-day Snow Cover (MOD10A2)
Software Affected PGE45
Processing String to Receive the Change Terra Forward, Terra Reprocessing, Aqua Forward
Downstream Product Effects The MOD10A2 correction will be propagated to MOD10C2.
Data Granules to be Used for Science Testing h11v03, h11v04, h12v03, h12v04 days 2000-052 - 2000-145.
Justification Correction will result in proper mapping of snow/ice covered lakes and inland waterbodies thus improved ability to track lake ice breakup timing and conditions.
Effective Date for Implementation of Change Data day 2000-049 for C5 Terra Reprocessing.
Data day 2007-001 for C5 Terra and Aqua Forward Processing.
