Final Report for Grant DE-FG02-90ER61072

This is the final report for the work done by our research group at the Atmospheric Sciences Research Center for the US DOE Atmopheric Radiation Measurement (ARM) Program. We were involved from the beginning of the ARM effort; we designed the Multi-filter Rotating Shadowband Spectroradiometer (MFRSR) which was widely deployed (and still operational in ARM) and through the years did a wide variety of data analysis on the returned data from these instruments. We also developed the Rotating Shadowband Spectroradiometer, which ARM deployed and also still deploys. Many scientific papers have been written using the data from these instruments, and the ongoing data streams remain part of the current ARM effort. Earlier reports contain our progress from previous grant periods, this report covers the last period and provides references to published work
