SINOPTICA in this period is performing the agreement with the EUMETSAT Radio Occultation Meteorology Satellite Application Facility (ROM SAF – https://www.romsaf.org/index.php) to assimilate the MetOp near real time radio occultation profiles into the WRF nowcasting model. The Radio occultations will provide the vertical atmospheric information in extreme conditions which is usually missing from the standard models. The access to the ROM SAF near real time data will provide the profiles with less than 1,5h of latency, optimal delay for nowcasting purposes.
