CAMEX-4 Shared Mobile Atmospheric Research and Teaching Radars Table of Contents
The Convection And Moisture EXperiment (CAMEX) is a series of field research investigations sponsored by the Earth Science Enterprise of the National Aeronautics and Space Administration (NASA). The fourth field campaign in the CAMEX series (CAMEX-4) ran from 16 August to 25 September, 2001 and was based out of Jacksonville Naval Air Station, Florida. CAMEX-4 focused on the study of tropical cyclone (hurricane) development, tracking, intensification, and landfalling impacts using NASA-funded aircraft and surface remote sensing instrumentation. The Shared Mobile Atmospheric Research and Teaching Radars (SMART-R) program is a collaborative research program involving four major weather research institutions: National Severe Storms Laboratory, Norman, Oklahoma, Texas A&M University, College Station, Texas, Texas Tech University, Lubbock, Texas, and the University of Oklahoma, Norman, Oklahoma. With two truck mounted weather radars, researchers can position themselves at short notice close to interesting meteorological phenomena. All equipment- antenna, power generator, processors and readout computers are truck mounted to provide maximum transportability. Originally located in the Florida Keys during CAMEX-4, the radar was moved to the Venice Florida area for landfall of TS Gabrielle on 14 Sept. Instrument DescriptionSpecifics of the SMART-R are shown in the table below.
Data are archived in a format which requires the use of the SIGMET IRIS radar program. This commercial program is available from SIGMET. Contact them directly with questions about obtaining the IRIS program. For those users who have access to SIGMET IRIS, we have the raw data files available for download via HyDRO. Technical support for these data is available as noted in paragraph 5 below. Browse imagery is also available via HyDRO. Data are 'tarred' into daily data files of the form:
where c4gsmart represents CAMEX4 and the SMART radar, and jjj is the day of year. When untarred, this will yield numerous data files for use in the SIGMET IRIS program. File naming convention for these data files is:
where c4gsmart identifies the experiment and instrument, yyyy.jjj is the four digit year and day of the year, SR1 indicates that this instrument is the #1 SMART radar, yymmddhhmmss indicates year, month, date, hour, minute and seconds in UTC that the data were collected. The file name extension is used in the IRIS program. Again, this file is in SIGMET IRIS format, and may be read using their radar program. See their homepage at SIGMET. Browse imagery files are named as:
with nomenclature similar to that shown in the data files. Imagery files may be viewed with any common viewer. Contact InformationAddress Scientific issues to:
