© Crown copyright Met Office B400 flight (18 Sept 2008) 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 Summary and future work Preliminary analysis of ARIES nadir data over ocean (zenith data may be subject to calibration biases) B400 case: small brightness temperature biases in (self continuum dominated) longwave window; larger biases in (foreign broadened) strong midwave band Future work: estimate uncertainties in atmospheric profiles and ARIES radiances Include collocated IASI radiances from MetOp overpass in data analysis Corroborate results by comparing with other flight days Intercompare results from ARIES, TAFTS and NPL FTS
