Description	Derived from precipitation maps generated by merging MW images from operational sun-synchronous satellites and IR images from geostationary satellites (i.e., products PR-OBS-3 and PR-OBS-4). Presented in polar stereographic projection. Coverage: The rectangular area of the stereographic projection that includes the H-SAF area [25-75°N lat, 25°W-45°E long] Cycle: Each 3 hours: MW+IR integrated over the previous 3, 6, 12 and 24 Resolution: Average over Europe: 8 km intended as sampling, ~ 30 km effective (controlled by the resolution of MW data) Accuracy: From PR-OBS-3 or PR-OBS-4: 40 % (lower bias from PR-OBS-4). More accurate for 24-h than for 3-h integration Timeliness: At fixed times of the day, within 15 min after synoptic hours (00, 03, 06, 09, 12, 15, 18 and 21 UTC) Dissemination: By dedicated lines to centres connected by GTS - By EUMETCast to most other users, especially scientific Formats: GRIB - Also JPEG or similar for quick-look
