MetopC IASI and MHS\/AMSU data are used to create NUCAPS profiles and that thermodynamic profiles are now flowing into AWIPS, as shown in the screen capture above that shows a NOAA-20 swath extending from Greenland to Alaska at about the same time as a MetopC swath that extends from the Atlantic to Greenland. The NOAA-20 and MetopC orbits are shown below (from this site<\/a>). The NOAA-20 orbit<\/a> stretches from Scotland (at 1255 UTC) to the Aleutians (1315 UTC); The MetopC orbit<\/a> is from the Arctic Ocean north of Scandanavia (about 1245 UTC) to the western Atlantic (around 1255 UTC).<\/p>\n\n\n\n

A power of NUCAPS from multiple satellites at higher latitudes is shown below. Over western Greenland, NOAA-20 and MetopC have sampled the same atmosphere at nearly the same time. What do those two points circled in blue show (the southernmost one is from NOAA-20, the northernmost from MetopC). That is shown below.<\/p>\n\n\n\n

At lower latitudes (over CONUS for example), the power of a second satellite means that earlier observations occur. MetopC orbits (here<\/a>) and NOAA-20 orbits (here<\/a>) over CONUS on 11 March show an east-coast pass at 1440 UTC (MetopC) and then one at 1755 UTC (NOAA-20); a central US pass at 1620 UTC (MetopC) and then one at 1935 UTC (NOAA-20); and a west coast pass at 1800 UTC (MetopC) and then one at 2120 UTC (NOAA-20). Thus, the temporal change of the atmosphere is more easily monitored.<\/p>\n\n\n\n

Sounding availability at 1552 UTC is shown below. NUCAPS profiles over central North America are from MetopC. NUCAPS profiles over Atlantic Canada are from NOAA-20.<\/p>\n\n\n\n
