The purpose of the NASA Portable S-band Multiparamerer Weather
Research Radar (NPOL) is to measure vertical distribution of radar
reflectivity and rainfall rates.
Other Information:
Platform: KAMP
Temporal Resolution: Continuous operation, full volume scans every ten
minutes, special scans to support aircraft operations
Spatial Resolution: 300 Km long range scans, 150 Km range for most
high resolution data scans. 150 m range resolution, 1.5 degree beam
width so the sample volume increases with range
Data Volume Per Day: 2 GB (estimate) 140 full volume scans, 140
surveillance scans per day
In-Field Quick Look Products: Real time PPI scans of reflectivities
and velocities, near real time displays of all radar products,
including RHI's,
CAPPI's, and Polarimetric products. Gif images of the radar displays
can be sent via the Internet in near real time.
Direct Products: Raw radar files along with a list any corrections
needed for calibration
Derived Products: None planned since raw files can be used to generate
any product of interest.
Potential Products: For case studies - full product suites can be
produced including calibrated reflectivites and line of sight
velocities, differential reflectivity, differential phase, and linear
depolarization ratios. Derived products can include rain rates and
hydrometeor classifications.
Preferred Aircraft Maneuvers: Flying along radials to the NPOL
Frequency of Maneuvers: Whenever feasible
Unfavorable Aircraft Maneuvers: Flying data flights directly over NPOL
(radar can not go past 90 degrees in elevation and if the plane takes
data while flying over the radar, radar data will be lost while the
antenna is rotated 180 degrees in azimuth)
Unfavorable Environmental Conditions: Hurricane force winds at the
radar location
Dropsondes Requested Per Mission: 1-2 in the aircraft mission area
with in range of NPOL
Preferred Atmospheric Conditions All weather conditions
Aircraft to Perform Drop: no preference
Desired Data Sources: Microphysical, radar (S,C and X-band), sondes,
profiler, disdrometers and raingauges
Mission Planning Needs: WSR-88D, Internet access, communications
