Satellite cloud and precipitation assimilation at operational NWP centres (2011, unknown): “Both the Advanced Infrared Radiation Sounder (AIRS; since 2002) and Infrared Atmospheric Sounding Interferometer (IASI; since 2006) are used fairly consistently across operational NWP centres in terms of channel selection, data screening and impact (Collard and McNally, 2009).”
On the representation error in data assimilation (2018, unknown): “Most commonly, the satellite radiances are used in clear-sky conditions only and a clear-sky radiative transfer model serves as the observation operator (e.g. Collard and McNally, 2009; Bormann et al. , 2013).”
Estimates of spatial and interchannel observation‐error characteristics for current sounder radiances for numerical weather prediction. I: Methods and application to ATOVS data (2010, background): “Both are applied widely in data-assimilation systems (Dando et al., 2007; Collard and McNally, 2009).”
Satellite-Based Atmospheric Infrared Sounder Development and Applications (2017, background): “…assimilated at many operational NWP centers, such as the European Centre for Medium-Range Weather Forecasts (ECMWF; McNally et al. 2006; Collard and McNally 2009; Cardinali 2009; McNally et al. 2014), the National Centers for Environmental Prediction (NCEP; Le Marshall et al. 2005, 2006a,b),…”
The ERA5 global reanalysis (2020, background): “B; Collard and McNally 2009) were also assimilated.”
