© Crown copyright Met Office First look at Camborne data Stuart Newman Reading, 25 November 2008

© Crown copyright Met Office B400 flight Best clear sky conditions encountered – no need for cloud hole hunting ARIES and TAFTS seemed to operate well Reasonably stable atmospheric structure High aerosol loading but IR measurements insensitive to this

© Crown copyright Met Office A quick look at the data FL340 (250 hPa)FL290 (314 hPa) FL145 (583 hPa) Select only nadir views over ocean to north of Camborne Use dropsonde profile launched from FL340 in line-by-line simulations SST from low level (100 ft) ARIES data

SST variability Northern data segment used in simulations

Future work (for discussion) Identify microwindows most sensitive to wv continuum Estimate uncertainties in atmospheric profiles and ARIES radiances Include collocated IASI radiances from MetOp overpass in data analysis Corroborate any results by comparing with other flight days Intercompare results from ARIES, TAFTS and NPL FTS
