摘要: Abstract A satellite-based 1° by normalized difference vegetation index (NDVI) data set has been processed to derive land surface parameters for general circulation models of the atmosphere (GCMs). Prior calculation parameters, corrections were applied source NDVI account (i) obvious anomalies in time-series, (ii) effect variations solar zenith angle, (iii) dropouts cold regions where a temperature threshold procedure designed screen clouds also eliminates points, and (iv) persistent cloud cover tropics. An outline procedures calculating from corrected is given, brief description provided material that was used addition data. The sets summarized this paper should represent improvements over prescriptions currently parameterizations spatial temporal dynamics key ...
