After earning his Ph.D. in Atmospheric Science from Colorado State University in 1991, Tom primarily engaged in creating NCDC's global
land surface data set used to quantify long - term global climate change.
In addition, as land surface heterogeneity is a crucial part in high - resolution modeling especially with respect to land surface changes, we want to dedicate a larger part of the input data session to efforts of generating high - resolution
land surface data sets (and time series of these) applicable as lower boundary conditions in atmospheric reanalysis systems as well as in coupled reanalysis approaches.
