The finer resolution and inclusion of CO2 and O3 as variable gases clearly improve the CRTM SSU simulation. J. Quant. Channels 1 and 3 show similar trends although the magnitude may be different. Since the carbon dioxide concentration in the atmosphere increased from 335 to 381 ppmv from 1978 to 2006 during the SSU observation period, the CO2 profiles in the training set have been adopted and extended to the required CO2 concentration ranges from their original values by scaling. In addition, the study revealed that the spectral resolution of 2.5 × 10−3 cm−1 for the SRF calculation in channel 3 is not adequate and could result in 0.6 K brightness temperature errors on average. Three other spectral resolutions (5 × 10−4, 1 × 10−3, and 2.5 × 10−3 cm−1) are used for the comparison. 3756), 277–288, Validation of the Aura Microwave Limb Sounder temperature and geopotential height measurements, A comparison of model-simulated trends in stratospheric temperatures, Temperature trends derived from stratospheric sounding unit radiances: The effect of increasing CO, An overview of the AIRS radiative transfer model, Radiometer for remote sounding of the upper atmosphere, JCSDA community radiative transfer model (CRTM), Beijing, China, World Meteorological Organization, 217–222, Report of the International Ozone Trends Panel 1988, Global Ozone Research and Monitoring Project Rep. 18, 829 pp, Scientific assessment of ozone depletion: 2006, Global Ozone Research Monitoring Project Rep. 50, 572 pp, Bulletin of the American Meteorological Society, Journal of Applied Meteorology and Climatology, Journal of Atmospheric and Oceanic Technology, http://www.ecmwf.int/publications/library/do/references/show?id=88508, Chart I.

To study the impact of cell pressure change and especially for fitting the cell pressures for SSU NOAA-7 channel 2 in section 5, a SSU pseudo sensor with cell pressure range covering all SSU sensors (cell pressures range from 105 to 118 hPa for channel 1, 14.8 to 46 hPa for channel 2, and 5 to 18 hPa for channel 3) has also been created and its transmittance coefficients generated. padding: 0; The double BT differences using the original cell pressures and fitting method 1 are obviously inconsistent before and after June 1983. Tu prépares un BTS (brevet de technicien supérieur) et tu te poses des questions par rapport à l’inscription aux épreuves pour obtenir le diplôme ? To accurately estimate brightness temperatures for the SSU, the RT model must include schemes to model the CO2 cell transmittance for each of the three channels and account for the variations of the SRFs caused by the CO2 cell pressure variations. The correlated scatterplots between the simulations and observations for NOAA-7 are also shown in Fig. Le BTS est une formation professionnalisante courte de niveau bac+2. We should point out that when considering the earth curvature effects by varying the zenith angle with height, the improved CRTM SSU model (version 2) always produces larger BTs than the previous version under same conditions.
