<title>New directions 2002 in software products for atmospheric remote sensing</title>

The Ontar Corporation (www.Ontar.com) is well known for its products for atmospheric remote sensing to calculate radiative transport, atmospheric transmission, and sensor performance in both the normal atmosphere and the atmosphere disturbed by battlefield conditions of smoke, dust, explosives and turbulence. This paper will describe new research activities at Ontar to enhance both the user capabilities and the model functionality. Ontar has incorporated new models into our software products and has initiated an ambitious IR&D effort to further enhance the models. This paper will discuss these efforts. We will also discuss new software products and updates to existing software products that we are distributing. This includes a new release of NVTherm; updates to PcModWin and PcLnWin; and a high resolution gas absorbance spectral database from the Pacific Northwest National Laboratory's (PNNL) spectral data library.
