NOAA WP3D AIRCRAFT - LOWER FUSELAGE RADAR COMPOSITES AND ZEBRA SATELLITE IMAGESD. Jorgensen (NOAA/NSSL, USA)Announced availability: 1 June 1993 Data AccessNOAA WP3D Lower Fuselage (LF) radar composites and Zebra satellite photos with flight tracks (as X-window dumps) are available via anonymous FTP from mrd3.mmm.ucar.edu in subdirectories /pub/TOGA-COARE/LF_cmps (radar imagery) and /pub/TOGA-COARE/zeb (satellite photos).
BackgroundDuring the four-month field phase of TOGA COARE, the two NOAA WP3Ds (P3s) operated out of Honiara in the Solomon Islands conducting 22 and 23 individual sorties for a total of 374 flight hours. Missions were conducted over a wide spectrum of weather from near "clear sky" to highly disturbed. Nearly 80% of the flight sorties were within the Intensive Flux Array (IFA); however, except for a three-day period from 12 to 15 December 1992, most of the convectively active missions were outside this region.The majority of the missions were a mix of boundary layer and convective flight patterns depending upon the weather. Prior to mid-February, most of the convective patterns were at night, which precluded the collection of a large amount of boundary layer data. After mid-February, the convective missions were conducted during daylight hours so boundary layer and Doppler data were collected simultaneously. For each convective mission during TOGA COARE, satellite imagery and LF radar composites were prepared that can be viewed via the XWUD command on a UNIX X-station. The satellite photos and flight track files were constructed in Honiara, using NCAR's Zebra software and saved as X-window screen dumps. The LF composites were constructed by John Daugherty from the radar tapes after each mission. Note that the individual files are stored in compressed format in subdirectories that are organized by date.
