26 In support of the <a href="http://trmm-fc.gsfc.nasa.gov">Tropical Rainfall
27 Measuring Mission</a>'s (TRMM) <a href="http://trmm-fc.gsfc.nasa.gov/trmm_gv/index.html">Global
28 Validation Program</a>, the NASA TRMM Satellite Validation Office has developed a Radar Software
29 Library for working with the various input radar formats. This is an object-oriented
31 <p>This library is an object oriented programming environment for writing
32 software applicable to all RADAR data related to the <a href="http://trmm-fc.gsfc.nasa.gov/trmm_gv/index.html">TRMM
33 GV</a> effort. This library reads the WSR88D, Lassen, Sigmet, McGill, UF,
34 HDF, RADTEC and native RSL file formats. Additional functions are
35 provided to manipulate the RSL objects. Nearly all of the functions return
36 objects. When they don't, they usually perform actions like output, making
37 images, etc. The most general object in RSL is <b>Radar</b>. The structure
39 is the method used to define the ideal or universal radar representation
40 in RAM while keeping the natural resolution of the data unchanged. More
41 simply, <b>Radar</b> represents the super set of all radar file formats.
42 The <a href="RSL_structures.html">Radar structure</a> is hierarchically
43 defined such that it is composed of <b>Volumes</b>, each containing one
44 field type. <b>Volumes</b> are composed of <b>Sweeps</b>.
46 are composed of <b>Rays</b> and <b>Rays</b> contains a vector of the field
47 type. Some field types are Reflectivity(DZ), Velocity(VR), Spectrum Width(SW),
48 etc. There are approximately 20 field types. See the
