“…Two Proteus flights dedicated to AIRS validation and flown over Potenza were scheduled precisely at the time when the Aqua satellite was also passing over Potenza during the nights of 7 and 9 September 2004. During the second phase over the UK, the Proteus aircraft, together with the UK Facility for Airborne Atmospheric Measurements (FAAM) BAE 146 aircraft (Taylor et al, 2007), made two flights dedicated to AIRS validation during the days of both 14 and 18 September 2004. Numerous in situ sensors and remote-sensing instruments flew on the BAE 146 aircraft, and dropsondes were released from the BAE 146 during the experiments.…”

“…Proteus and BAE 146 were flying at approximately the same location and time for these two dates. A series of five and nine dropsondes were released from BAE 146 in a close location and time on 14 and 18 September, respectively (Taylor et al, 2007). Figure 7 shows the different atmospheric conditions from day to day captured by the measurements.…”

“…Because these two cases were made with the BAE 146 aircraft flying as low as 30 m above the sea, the surface properties, like the sea surface temperature (SST) and emissivity, are observed with the Airborne Research Interferometer Evaluation System (ARIES) on board (e.g. Newman et al, 2005;Taylor et al, 2007). NAST-I and ARIES observations within the AIRS FOV are used for intercomparisons.…”

“…An international experiment, European Aqua Thermodynamic Experiment (EAQUATE), performed in both Italy and the United Kingdom during September 2004, demonstrated certain ground-based and airborne systems useful for validating hyperspectral sounding observations from satellites throughout this decade and the next. The focus of this initial experiment was primarily placed on the validation of the AIRS instrument data from the EOS Aqua satellite (Cuomo et al, 2005;Smith et al, 2005b;Taylor et al, 2007). A great deal of effort has been given to the data collected during EAQUATE.…”

Atmospheric and surface thermodynamic parameters retrieved with advanced hyperspectral remote sensors aboard Earth observing satellites are critical to weather prediction and scientific research. The retrieval algorithms and retrieved parameters from satellite sounders must be validated to demonstrate the capability and accuracy of both observation and data processing systems. The European Aqua Thermodynamic Experiment (EAQUATE) was conducted not only for validation of the Atmospheric InfraRed Sounder on the Aqua satellite, but also for assessment of validation systems of both ground-based and aircraft-based instruments that will be used for other satellite systems, such as the Infrared Atmospheric Sounding Interferometer on the European MetOp satellite, the Cross-track Infrared Sounder from the National Polar-orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project and the continuing series of NPOESS satellites. Detailed intercomparisons were conducted and presented using different retrieval methodologies: measurements from airborne ultraspectral Fourier transform spectrometers, aircraft in situ instruments, dedicated dropsondes and radiosondes, ground-based Raman lidar, as well as the European Centre for Medium-range Weather Forecasting modelled thermal structures. The results of this study not only illustrate the quality of the measurements and retrieval products, but also demonstrate the capability of the validation systems put in place to validate current and future hyperspectral sounding instruments and their scientific products.

“…Specifically, this experiment aimed to illustrate to what extent the combined use of ground-based and airborne systems is beneficial for a correct validation strategy. During the Italian phase of EAQUATE (6-10 September 2004), a variety of ground-based instruments were operated in coordination with airborne remote-sensing instruments on board the NASA research aircraft Proteus, which performed several flights over the ground-based stations and along the AQUA ground track (Taylor et al, 2007).…”

Three lidar stations located in Southern Italy were operational during the Italian phase of the EAQUATE campaign in September 2004. With this cluster of instruments, the characterization of water vapour and clouds distribution and evolution with high temporal and vertical resolution is possible. A cirrus cloud episode and the presence of an elevated humid layer in the free troposphere observed at all three stations are analysed in detail. Variability of both cirrus cloud and water vapour fields is studied on different spatial and temporal scales.

The Joint Polar Satellite System (JPSS) Cross‐track Infrared Microwave Sounder Suite (CrIMSS) is an advanced operational satellite sounding system concept comprised of the Cross‐track Infrared Sounder and the Advanced Technology Microwave Sounder. These are synergistically designed to retrieve key environmental data records (EDR), namely atmospheric vertical temperature, moisture, and pressure profiles. CrIMSS will serve as the low‐Earth orbit satellite sounding system, starting with the Suomi National Polar‐orbiting Partnership (S‐NPP) satellite and spanning the JPSS‐1 and JPSS‐2 satellites. This paper organizes the general paradigm for validation of atmospheric profile EDR retrieved from satellite nadir sounder systems (e.g., CrIMSS) as a synthesis of complementary methods and statistical assessment metrics. The validation methodology is ordered hierarchically to include global numerical model comparisons, satellite EDR intercomparisons, radiosonde matchup assessments (conventional, dedicated, and reference), and intensive campaign “dissections.” We develop and recommend the proper approach for computing profile statistics relative to correlative data derived from high‐resolution in situ data (viz., radiosondes) reduced to forward model layers. The standard statistical metrics used for EDR product assessments on “coarse layers” are defined along with an overview of water vapor weighting schemes and the use of averaging kernels. We then overview the application of the methodology to CrIMSS within the context of the JPSS calibration/validation program, with focus given to summarizing the core data sets to be used for validation of S‐NPP sounder EDR products.
