Cloudsat near-surface precipitation diagnostics #12

Closed dustinswales closed 5 years ago

dustinswales commented 6 years ago

This pull request contains new diagnostics for the Cloudsat radar simulator. The diagnostics are based upon the Cloudsat 2C-PRECIP-COLUMN observational product (http://www.cloudsat.cira.colostate.edu/data-products/level-2c/2c-precip-column).

This update is relatively minor, as the new diagnostics rely on fields already being provided by the cloudsat radar simulator. New diagnostics include the path integrated attenuation and the near-surface precipitation frequency, by class/type. Unlike the observational product, the near-surface mixing-ratios, used by the melting layer model, are not computed using radar reflectivities, but are rather provided by the model and hence are not output as part of the new diagnostics in COSP.

@dustinswales please can you copy and past the outputs of the standard tests so that we have a record of them in all the pull requests? Thanks!
