Introduction

The CAMEX-4 MIPS Microwave Profiling Radiometer dataset includes data from the University of Alabama in Huntsville (UAH) Mobile Integrated Profiling System (MIPS), a mobile atmospheric profiling system; data was acquired during the CAMEX-4 campaign that took place August – September 2001. The MIPS instrument 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, approximately, every 15 minutes; cloud base temperature is also measured. 15 minute profiles were put into daily data files, in ASCII file format. The spatial coverage area for the dataset is N: 24.7, W: 81.6.

Campaign

The Convection And Moisture EXperiment (CAMEX) was a series of field research investigations sponsored by NASA's Earth Science Enterprise. CAMEX-4 was the fourth field campaign in the CAMEX series; it took place from August 16, 2001 through September 24, 2001 and was based out of the Jacksonville Naval Air Station in Jacksonville, Florida. The focus of the campaign was the study of tropical cyclone development, tracking, intensification, and landfalling impacts using NASA-funded aircraft and surface remote sensing instrumentation. The primary aircrafts used during CAMEX-4 included the NASA DC-8 and ER-2 research airborne platforms. The aircrafts flew over, through, and around certain hurricanes as they approached landfall in the Caribbean, Gulf of Mexico, and along the east coast of the United States. Measurements were compared and validated with satellite observations when available. The study results aided hurricane modelers and forecasters in improving hurricane prediction accuracy.

Instrument Description

The Mobile Integrated Profiling System (MIPS) is a mobile atmospheric profiling system developed by the University of Alabama in Huntsville (UAH). 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 Microwave Profiling Radiometer (MPR) is a microwave radiometer that measures profiles of temperature, water vapor, cloud water, and column integrated values of water vapor and cloud water at 10 minute intervals up to 10 km with the highest vertical resolution at low levels. This system also includes an infrared pyranometer which measures cloud base temperature. More information about MIPS, including pictures, is available here http://vortex.nsstc.uah.edu/mips/system/.

File Naming Convention

The Microwave Profiling Radiometer dataset is available in ASCII file format. Data files were named with the following convention:

c4gmipmpr_YYYY.DDD.dat

Where,

c4gmipmpr = CAMEX-4 Mobile Integrated Profiling System (MIPS) Microwave Profiling Radiometer
YYYY = year of the data
DDD = Julian day of the data
.dat = ASCII file type

Data Format

The CAMEX-4 MIPS Microwave Profiling Radiometer dataset includes 15 minute profiles put into a daily ASCII file. Profiles of temperature, water vapor and liquid water, and integrated values of water vapor and liquid water from the surface to 10km is included in the data files.
