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