Aerosol microphysics retrievals
Preliminary microphysics and ocean data products from HSRL-1 and HSRL-2 co-located Research Scanning Polarimeter (RSP) measurements will be available by downloading the "RSP-MAPP-aerosol-alpha-*" HDF5 files from the NASA GISS RSP website. The retrieval methodology is described in the paper [1] with comparisons to HSRL-1 and HSRL-2 products including AOD, lidar ratio, HSRL-2 355/532 Angstrom exponent, and HSRL-1 ocean measurements. Campaigns processed: TCAP, SABOR.

Ocean retrievals
HSRL-1 is capable of measuring depth-resolved in-water backscatter and diffuse attenuation coefficients at 532 nm.

TiARA for lidar retrievals of aerosol optical and microphysical parameters
Tikhonov Advanced Regularization Algorithm (TiARA) is used for the analysis of data acquired by the NASA Langley Research Center (LaRC) High-Spectral Resolution Lidar (HSRL-2). The purpose of TiARA is to retrieve the aerosol microphysical parameters using HSRL-2 data, and thus to offer a possibility of obtaining the quantitative measure of the spatial and temporal variation of aerosol properties. The outputs of TiARA are the numerous microphysical parameters that can be used for the comparisons with the results of measurements of in situ and remote sensing instruments, and for other related purposes. All the delivered aerosol products are vertically resolved. The vertical resolution of aerosol parameters is critical for some atmospheric applications like, for instance, climate modeling.    + Download the TiARA ATBD PDF Document
