The CAMEX-4 ER-2 Microwave Temperature Profiler dataset was collected by the Microwave Temperature Profiler (MTP), which is a passive microwave radiometer which measures the thermal emission from oxygen molecules in the atmosphere for a selection of elevation angles. Current observing frequencies are 56.6 and 58.8 GHz. Measured brightness temperature versus elevation angle is converted to air temperature versus altitude using a statistical retrieval procedure. An altitude temperature profile is produced every three km along the flight path. Data were collected from the Jacksonville Naval Air Station, Florida during the CAMEX-4 campaign spanning from August 26 - September 26. 2001.

The CAMEX-4 DC-8 Microwave Temperature Profiler (MTP) dataset was collected by the MTP, which is a passive microwave radiometer used during the CAMEX-4 campaign to collect data measurements of thermal emmission from oxygen molecules in the atmosphere for a selection of elevation angles. Current observing frequencies are 56.6 and 58.8 GHz. Measured brightness temperature versus elevation angle is converted to air temperature versus altitude using a statistical retrieval procedure. An altitude temperature profile is produced every three km along the flight path. These data were collected from August 16 - September 25, 2002 from Jacksonville Naval Air Station, Florida.

The TCSP ER-2 Microwave Temperature Profiler (MTP) dataset was collected by the ER-2 Microwave Temperature Profiler (MTP), which is a passive microwave radiometer which measures the thermal emission from oxygen molecules in the atmosphere for a selection of elevation angles (normally 10 between +60 and -58 degrees). The current observing frequencies are 55.5, 56.6 and 58.8 GHz. Measured 'brightness temperature' versus elevation angle is converted to air temperature versus altitude using a modified statistical retrieval procedure with a Bayesian component. An altitude temperature profile (ATP) is produced in this manner every 13 seconds or approximately 3 km along the flight path. The ATP can be used to produce a color-coded temperature curtain (CTC) of the temperature field which the ER2 has flown through, and to identify the tropopause location. ATPs can also be used to locate altitudes where the air is cold enough to condense nitric acid or water vapor to form polar stratospheric clouds (PSCs). The TCSP mission collected data for research and documentation of cyclogenesis, the interaction of temperature, humidity, precipitation, wind and air pressure that creates ideal birthing conditions for tropical storms, hurricanes and related phenomena. The goal of this mission was to help us better understand how hurricanes and other tropical storms are formed and intensify.

The CAMEX-4 AMPR Brightness Temperature (TB) dataset was collected by the Advanced Microwave Precipitation Radiometer (AMPR), which was deployed during the Fourth Convection and Moisture Experiment (CAMEX-4). AMPR data were collected at four microwave frequencies (10.7, 19.35, 37.1 and 85.5 GHz) for the period of 26 August 2001 through 24 September 2001. The purpose of the CAMEX-4 mission was to study hurricanes over land and ocean in the U.S., Gulf of America, Caribbean, and Western Atlantic Ocean in coordination with multiple aircraft and research-quality radar, lightning, and radiosonde sites.

The CAMEX-3 ER-2 NPOESS Aircraft Sounder Testbed - Microwave Temperature Sounder (NAST-MTS) dataset contains navigation records and microwave spectral radiance measurements taken of tropical cyclones and hurricanes during the third Convection and Moisture Experiment (CAMEX-3). The NAST-MTS contains two microwave radiometer systems covering the spectral ranges of 50 to 56 GHz and provides atmospheric temperature profiles from the flight altitude to the surface.

The Advanced Microwave Precipitation Radiometer (AMPR) was deployed during the Convection and Moisture Experiment 2 (CAMEX-2). AMPR data were collected at a combination of frequencies (10.7, 19.35, 37.1, and 85.5 GHz) during the time period of August 23 - August 30, 1995. The geographic domain of the CAMEX-2 region was between 25.5 N - 43 N latitude and 83 W - 70 W longitude.

The University of Alabama in Huntsville (UAH) Mobile Integrated Profiling System (MIPS) is a mobile atmospheric profiling system. It includes a 915 MHz Doppler profiler, lidar ceilometer, 12 channel microwave profiling radiometer, Doppler Sodar, Radio Acoustic Sounding System (RASS), Field Mills, and surface observing station. The 12 channel microwave profiling radiometer provides profiles of temperature, water vapor and liquid water and integrated values of water vapor and liquid water from the surface to 10km every ~ 15 minutes. Cloud base temperature is also measured.
