Description

Since our last report in 2016, the ARM Cimel Sun Photometers (CSPHOT) have experienced several new developments. The deployment to Antarctica (McMurdo, and WAIS) presented challenges that had to be overcome. We now have gathered cloud mode (zenith sky radiance) data for the first time in Antarctica. Four new model CE318-T Sun Photometers have arrived with the added capability of acquiring the moon and hence obtaining aerosol optical depth at night. This will be of particular interest at our Arctic sites (NSA and OLI). But before they can be deployed they need to be calibrated at AERONET and their low-temperature limit evaluated. We have made progress on new data products for the calibrated sky radiances and retrievals of cloud optical depth and cloud drop effective radius.
