Three minor updates were made to the options used by CMAQ to drive air-surface exchange processes.
- The option for diagnostic output of dry deposition velocities was added for CB6 species IOLE, APIN, EPOX, and NAPH.
- Specification of MEDIACONC output from the previous day was corrected in the default run scripts.
- The calculation of land-water fraction was updated to correctly consider grid cells that are entirely snow/ice.
- Dry deposition velocties are now output for these species.
- CMAQ will correctly initialize the model with the soil properties from the previous midnight rather than starting from clean conditions.
- Grid cell areas covered in snow/ice will no longer count as water, thereby avoiding instabilities in the algorithm that requires normalizing by the land area fraction.
