In this study, we first evaluated insolation products against surface pyranometer observations for selected periods of 2006, 2012, and 2013 to identify and address some of the systemic problems. Lack of a robust technique to account for satellite sensor degradation and the use of constant precipitable water were identified as major problems. By addressing these issues and incorporating the latest improvements in the retrieval algorithm, the data was reprocessed and evaluated. Additionally, an algorithm for estimating photosysnthetically active radiation (PAR) was developed and PAR was generated/evaluated and added to the suite of products to be archived. The new retrievals were used in air quality simulations using WRF/SMOKE/CMAQ modeling system for selected periods of 2012 and 2013. For these simulations GOES-derived cloud products were assimilated in WRF and GOES-based PAR was used in biogenic emission estimates. The preliminary results from these simulations, as well as evaluation of the new products will be presented.
