Janice joined the ESRL/PSL Hydrometeorology Modeling and Applications Team as a Research Scientist in March of 2017. Her research interests focus on the atmospheric components of the global hydrologic cycle, specifically examining ways in which we can better observe and represent these components at a variety of spatial and temporal scales. Her previous work has focused on remotely sensed observations of precipitation and column water vapor, including production of the NASA Water Vapor Project - MEaSUREs (NVAP-M) global water vapor climate data record.

Janice's current work centers on the validation of precipitation forecasts from high resolution models, with the intent to relate forecast quality to model processes and assumptions. She has assessed forecasts of convective precipitation from the HRRR model over the Central US, and is continuing that work over the Bay Area of Northern California as part of the Advanced Quantitative Precipitation Information (AQPI) project.
