This is an encore of the GNSS-RO PRO presentation originally delivered at the American Meteorological Society Annual Meeting, now available as a recorded webinar so you can watch anytime.
This presentation is an overview of our calibration and retrieval process to isolate and geolocate the precipitation induced signatures. We will present our initial differential phase results, including determining the noise floor when no precipitation is present and comparisons with other collocated precipitation measurements and analyses such as IMERG and ERA5 snowfall which has been shown to correlate with the PAZ measurements.
We will provide an initial assessment of how the sensitivity and performance depends on SNR and other factors and the degree to which higher SNR enables detection of smaller amounts of precipitation and certain clouds. We will also present a summary of performance over land versus ocean and demonstrate the insensitivity of these measurements to variations in surface conditions and emissivity below that enable these observations to provide truly global coverage.
