LBA REGIONAL TREE COVER FROM AVHRR, 1-KM, 1992-1993 (DEFRIES ET AL.)
Entry ID:
lba_tree_cover
Summary
Abstract:
The data set consists of a subset for the study area of the Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) in South America (i.e., longitude 85 deg to 30 deg W, latitude 25 deg S to 10 deg N) of the 1km Global Tree Cover Data Set developed at the Laboratory for Global Remote Sensing Studies (LGRSS) at the University of Maryland. Data are available in both ASCII GRID and binary image ...

Quality
Satellite/gauge relative error estimates are provided for each 0.25 x 0.25 degree box. The estimates are derived in two steps: (1) the error estimates of each input data are computed separately, mostly reflecting the sampling-induced uncertainty of each field and (2) a linear combination of these field errors is computed, in which each field error estimate is weighted by the inverse of its error-variance. There are currently no known deficiencies in the 3B43 algorithm. The quality of the 3B43 product is highly sensitive to the quality of the input data: TRMM adjusted merged-IR (product 3B42) and monthly accumulated TMI/TRMM Combined Instrument (TCI, product 2A12/3B31). If the quality of the input data is less than anticipated, then the quality of 3B43 will also be less.
