Short summary
This study investigates the impact of increased Global Navigation Satellite System radio occultation (GNSS-RO) profiles on numerical weather prediction (NWP) as part of the Radio Occultation Modeling EXperiment (ROMEX) effort. Using the Joint Effort for Data assimilation Integration (JEDI), this impact study provides critical insights into the necessity of enhanced GNSS-RO observations for NWP applications.
