Investigating Precipitation and Aerosols Over Southeast Asia Using a Collocated CloudSat-CALIOP-MODIS-NAAPS Dataset

Satellite observations and model simulations cannot, by themselves, give insight into the complex relationships between aerosols and clouds. Here, we present a new data set designed to investigate these relationships that collocates three NASA A-Train instruments: CloudSat's Cloud Profiling Radar (CPR), the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP), and Aqua's MODerate-resolution Imaging Spectroradiometer (MODIS) providing coincident vertically resolved cloud, aerosol, and precipitation observations. Model re-analysis from the Navy Aerosol Analysis and Prediction System (NAAPS) is also included in the data set. An eight-year record (2006 - 2014) has been processed for the Southeast Asia region. The initial application will focus on investigating the observational relationships between the aerosol, cloud and precipitation within Southeast Asia. Comparisons with the NAAPS will also be presented.
