Abstract Introduces the L3 4-day LAI/FPAR (MCD15A3) and 8-day LAI/FPAR (MCD15A2) products.
Problem Statement Produce 4-day and 8-day Terra/Aqua Combined LAI/FPAR product.
Description of Change Apply standard composition scheme (used in Terra 8-day product) to generate 4-day (MCD15A3) and 8-day (MCD15A2) Combined Terra/Aqua products from corresponding 4 and 8 Terra and Aqua daily retrievals.
Products Affected L3 LAI/FPAR (MCD15A3, MCD15A2)
Software Affected PGE34, PGE94
Processing String to Receive the Change Terra Forward, Terra Reprocessing, Aqua Forward, Aqua Reprocessing
Downstream Product Effects None.
Data Granules to be Used for Science Testing 16-day global test, summer and winter time series.
Justification Combined 8-day product have about 10-15% improvement in coverage of high quality retrievals over woody vegetation compared to single sensor 8-day product. Combined 4-day product double temporal resolution compared to other products, the feature requested by users in ecological and climate applications.
Effective Date for Implementation of Change Data day 2001-001 for C5 Terra Reprocessing.
Data day 2007-001 for C5 Terra and Aqua Forward Processing.
Status PI approved. Sadashiva Devadiga approved for Land, Vincent Salomonsom approved on 12/27/06.
