Derivation of 2D fields of aerosol and trace gases parameters by integrated analysis of multi-instrument MFRSR datases from DOE ARM Program CART site

摘要

We present results from a preliminary analysis of the multi-instrument MFRSR dataset from ARM CART (SGP) site Extended Facilities (Northern Oklahoma and Southern Kansas). Single-instrument retrievals are performed using our previously reported direct-diffuse algorithm. Retrieval products include daily time series of the aerosol optical depth, column mean aerosol particle size, NO_2 and ozone column amounts. The distribution of MFRSR sites at the SGP (central and extended facilities) allows us to combine the retrievals from the individual instruments into series of 2D images. These 2D images facilitate the investigation of spatial and temporal variability of aerosols and trace gases. These images can be also used to evaluate satellite aerosol data products (e.g. MODIS, TOMS, EO-1).
