Evaluation of LES against satellite and ground-based observations

Evaluation of LES against satellite and ground-based observations#

  • The below notebook compares selected simulations against observational targets that were collected from satellite and ground-based retrievals.

  • In case of questions or concerns, please notify Ann Fridlind (ann.fridlind@nasa.gov), Timothy Juliano (tjuliano@ucar.edu), and Florian Tornow (ft2544@columbia.edu).
