The
Generic Mapping Tools (GMT) by Paul Wessel and Walter H. F. Smith
are a huge collection of tools to manipulate 2D and 3D
data sets (including filtering, trend fitting, gridding, projecting, etc.)
and to produce Encapsulated PostScript (EPS) illustrations ranging from
simple x-y plots through contour maps to artificially illuminated surfaces
and 3-D perspective views. GMT supports 25 common map projections plus
linear, log, and power scaling, and comes with support data such as
coastlines, rivers, and political boundaries. In combination with the
Global 30 Arc Second Elevation Data Set (GTOPO30),
topographic maps for any location of the world are easily created.
A graphical front-end,
iGMT (Interactive Mapping of Geoscientific Datasets), is also available.

MATPACK
is an advanced C++ library containing lots of numerical methods
and data visualization algorithms that are needed in a scientist's
or engineer's everyday life. The development of Matpack started in 1991
at the Physics Department of the Technical University of Munich, Germany.
Since then it rapidely grew to large collection of numerical
methods and interactive data visualization tools. Matpack is free for
non-commercial purposes. It has been ported to Linux PCs, DEC
Alpha, HP, and Sun workstations.

The
BSRN (Baseline Surface Radiation Network) at the
World Radiation Monitoring Center (WRMC) is a project of the
World Climate Research Programme (WCRP) aimed at detecting important
changes in the earth's radiation field which may cause climate changes.
At a small number of stations (fewer than 40) in contrasting climatic zones,
covering a latitude range from 80°N to 90°S (see station maps),
solar and atmospheric radiation is measured with instruments of
the highest available accuracy and at a very high frequency (minutes).

Atmospheric Radiation Measurement Program. The ARM Program
establishes and operates field research sites,
called Cloud and Radiation Testbeds
(CARTs), in several climatically significant
locations. Scientists collect and analyze data
obtained over extended periods of time from
large arrays of instruments to study the
effects and interactions of sunlight, radiant
energy, and clouds on temperatures, weather,
and climate.
