Alexandrov, M.D., A.A. Lacis, B.E. Carlson, and B. Cairns, 2001: MFRSR-based climatologies of atmospheric aerosols, trace gases, and water vapor. In Remote Sensing of Clouds and the Atmosphere V, 25 Sep. 2000, Barcelona, Proc. SPIE, vol. 4168, pp. 256, doi:10.1117/12.413872.

Measurements from ground-based sun photometer networks can be used both to provide a ground-truth validation of satellite aerosol retrieval sand to produce a land-based aerosol climatology which is complementary to satellite retrievals that currently are being performed mostly over ocean. The MFRSR has become a popular network instrument in recent years, several existing networks operate about a hundred instruments providing good geographical coverage of the US. We describe and validate a retrieval algorithm for processing MFRSR data from clear and partially cloudy days. This method uses consistency between direct normal and diffuse horizontal measurements together with a special regression technique for retrieval of daily time series of column mean aerosol particle size, aerosol optical depth, NO2, ozone and water vapor column amounts together with the instrument's calibration constants. This method has bene successfully used to analyze MFRSR measurements from a number of instruments both from large networks and those operated by individual users. The analysis of long-term MFRSR measurements provides a description of seasonal and inter-annual changes in aerosol parameters and in column amounts of ozone, NO2 and water vapor as a function of geographical location. Application of this analysis method to the measurements from growing numbers of MFRSR opens the possibility to build large-scale climatologies basing on MFRSR network data.
