Welcome to the NASA Langley Research Center Polarimetry Website
PACE-MAPP is a modified version of RSP-MAPP applied to combined measurements from the two polarimeters (SPEXone and HARP2) and OCI SWIR bands onboard PACE. PACE-MAPP will retrieve aerosol optical and microphysical properties of fine mode aerosols, coarse mode sea salt, and coarse mode dust and the ocean properties using a bio-optical model that incorporates absorption and scattering by coated particles. A unique aspect of PACE-MAPP is that we will be validating the ocean products using airborne HSRL ocean measurements.
The PolCube cubesat polarimeter is a multi-angle, multi-channel polarimeter that occupies 12 U after integration with the spacecraft bus. PolCube has 4 channels and 4 viewing angles per channel.
The SIR-A-LUT was developed for accurate and fast forward modeling of homogenous spheres for polarimeters and lidars (Lorenz-Mie theory). The databases can be downloaded from here for polarimeters (and spectroradiometers such as MODIS or OCI) and lidar. Code is available to read the databases in Matlab, C++, Fortran, and Python. (Suggestions and comments to improve these readers are welcome.)
