This python module reads 5 cm soil temperature (Tsoil) and volumetric
water content (VWC) from the Climate Forecast System (CFS) Version 2
(CFSv2) Reanalysis (CFSR; Saha et al (2010)).  Data are read for the
CFSR grid cells containing specified longitude and latitude
coordinates.  The data are read from the NOAA NOMADS system
(http://nomads.ncdc.noaa.gov/) via web connection.

The data are written to netcdf files, one file per location.

The "__main__" script defines the locations whose grid cells are to be
read, reads the data, writes the netcdf files, and produces a plot of
each time series read.
