Scatterplot of global monthly-mean measured BTs and simulated BTs using the fast model from the CIRA temperature profiles for SSU NOAA-7 channels at scan angle 5° for (top to bottom) channels 1–3. The SSU channel 3 has different double difference pattern compared with the other two channels because this channel senses upper stratosphere–lower mesosphere (lapse rate reverse) and relatively larger cell pressure differences compared to channel 1. Calculation Of Straight Line Depreciation - Return On Shareholder Investment. An interference filter then confines the spectral response, and contributions from any other radiation not originating from within the 15-μm region are neglected. Independent test results of CRTM SSU simulations compared with those from LBLRTM for UMBC 48 profile set. Two linear fitting methods are proposed to solve the larger brightness temperature gap between observation and model simulation using the available cell pressures for NOAA-7 channel 2 after June 1983. Bts cira coefficient. Climate, 12, 3197–3219. View More. With the three modulated cells, the weighting function of the original 15-μm carbon dioxide absorption band (with peak at around 70 hPa) is shifted up and split into 3 weighting functions with peak pressures of approximately 14.6, 4.6, and 1.9 hPa. Matricardi, M., 2008: The generation of RTTOV regression coefficients for IASI and AIRS using a new profile training set and a new line-by-line database. It includes components that compute the radiation from gaseous absorption, absorption and scattering of radiation by hydrometeors and aerosols, and emission and reflection of radiation by ocean, land, snow, and ice surfaces. Also, the O3 absorption cannot be neglected, especially for SSU channel 1 with mean difference about −0.1 K. The RT model is first validated against LBLRTM using independent UMBC 48 profile sets. Of these samples, 1786 are in January, 3771 are in April, 1969 are in July, and 3036 are in October. display: flex; Global Ozone Research Monitoring Project Rep. 50, 572 pp. A total of 10562 matched samples were collected for the comparison. display: flex; 14th Int. It is shown that the BT difference between the fast RT model and line-by-line model is less than 0.1 K, but the fast RT model is at least two orders of magnitude faster.

[Available from AFGL, Hanscom AFB, MA 01731. SABER has generally warm biases of ~2 K relative to MLS, and the ECMWF and Goddard Earth Observing System, version 5 (GEOS-5) analyses below 10 hPa (Schwartz et al. The RMS differences from the improved CRTM SSU model compared to LBLRTM are less than 0.1 K for the independent profiles. The authors thank Dr. Likun Wang for providing the SSU reading software and Dr. Haifeng Qian for NOAA-8 SSU data. 2006; Matricardi 2008) are used as training profiles. Since the SSU fast model is trained with ECMWF 83 profiles, it is necessary to test BT against the base LBLRTM on an independent data ensemble, the UMBC 48 atmospheric profile set. 1980). Therefore the ozone profiles are fixed and taken from the U.S. Standard Atmosphere, 1976. BTS has certainly done their share of giving back – in 2017, each member donated KR₩10,000,000 (roughly 8,950 USD) to the families of the 2014 Sewol Ferry Disaster. The average peak heights for each channel are given by the dash lines. 1988) (CIRA) with a 5° latitudinal resolution from 80°S to 80°N. Each set of coefficients are generated in a similar process as described in section 3. Tech. When using fitting method 2, the simulated temperature trend from channel 2 is consistent with the observation. 2003; Schwartz et al. Section 2 provides a brief discussion of the SSU instrument response, followed by an in-depth assessment of the sensitivity of spectral resolution and atmospheric gaseous absorption on SSU simulated radiances. 3 by using a CO2 concentration of 360 ppmv as a reference. Randel, W. J., and Coauthors, 2009: An update of observed stratospheric temperature trends. The previous version SSU fast RT model was developed at the Joint Center for Satellite Data Assimilation (JCSDA) in 2007 using the Compact–Optical Path Transmittance (OPTRAN) algorithm concept (McMillin et al. The model results show consistency and improvement compared with results from the previous SSU model using the MLS dataset. NOAA/NESDIS Center for Satellite Applications and Research, Camp Springs, MD 20746 . Comparisons of the SSU NOAA-14 BTs between the fast model and observations for (top to bottom) channels 1–3. 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. Science Application International Corporation, Camp Springs, MD 20746. 1 for (left) 5 model atmospheres including the MMLS, MMLW, MSAS, MSAW, and MTROP. In general, the effects cannot be neglected, and the temporal progress of those effects can substantially reduce the temperature trends seen in the observed data (Brindley et al. Return On Investment Calculator - Circle. From these transmittance spectra the channel transmittances are calculated by convolution with the channel SRF, computed with the LBLRTM version 11.3 and at a specified CO2 cell pressure.

The reference case uses a spectral resolution of 1 × 10−4 cm−1, and seven absorbers (H2O, CO2, O3, N2O, CO, CH4, and O2) in LBLRTM. Geophys., 39, 71–122. 7. 6. The improved SSU fast model can be applied for reanalysis of the observations. Channels 1 and 3 show similar trends although the magnitude may be different. The ODPS transmittance model is an optional transmittance model, along with the Compact-OPTRAN model, implemented within the multiple transmittance algorithms framework in the JCSDA Community Radiative Transfer Model (CRTM) version 2. The dots show the results for training spectral resolution 5 × 10−4 cm−1 and absorber gases including CO2 and O3, whereas the triangles show the results for spectral resolution 2.5 × 10−3 cm−1 and only including CO2 gas. (1999) reported that the calculated effects on BT ratio due to the cell pressure shifts are less than 0.1% for SSU channel 1 from 1979 to 1994. Thanks to three anonymous reviewers for their very useful suggestions to improve our paper. Linear fitting the ssu_n07 channel 2 cell pressures and predicting the cell pressures after June 1983. This impact is important for longer measurement periods as indicated by Shine et al. The finer resolution and inclusion of CO2 and O3 as variable gases clearly improve the CRTM SSU simulation. It can also be used to address two important corrections in deriving trends from SSU measurements: CO2 cell leaking correction and atmospheric CO2 concentration correction. Want to find out more? J. ECMWF Tech. This research was supported by funding from the Joint Center for Satellite Data Assimilation program. Soc., 129, 1565–1588.
