IHOP Operations Plan, Chapter 7:
Other Special Ground-Based
Instrumentation Operation
“Other special instruments” are non-mobile and nonscanning radar sensors. Two broad categories:
• Water vapor remote sensors:
Lidars, radiometers, GPS.
• Support instruments:
Profiler, flux towers, FM-CW radar.
IHOP Operations Plan, Chapter 7:
Other Special Ground-Based
Instrumentation Operation
Except for the FM-CW radar, all the instruments are
fixed and have few operating modes.  It’ll be quick.
• Water vapor remote sensors:
Lidars, radiometers, GPS.
• Support instruments:
Profiler, flux towers, FM-CW radar.
NASA Scanning Raman Lidar (SRL)
• Scanning lidar: RHI and
stares (mostly vertical).
• Measures water vapor
(day/night time range?).
• Deployed near Lamont?
• Manned operation (?),
unknown schedule.
• Data probably unavailable
in real-time to Ops Center.
• Will need basic operation
schedule from Ops Center,
probably nothing more.
NOAA Water Vapor DIAL
• Fixed-direction lidar.
• Measures water vapor
profiles up to about
“several” (TBA) kilometers.
• Unspecified deployment
location.
• Unattended operation.
• 24-hr operation.
• Data can be available with
1-hr delay to Ops Center.
• Limited or no need for
information from Ops
Center.
Microwave Profiling Radiometers
• Vertically pointing.
• Measures temperature,
water vapor profiles up to
about 10 km.
• Existing unit in Lamont;
new ones in Haviland (KS)
and Neodesha (KS).
• Automated 24-hr operation.
• Data can be made available
via Web, modem.
GPS Receiver Network for Tomography
• Array of 24 GPS receivers
• Measures refractivity N in a
~5x5 km array; water vapor field
is derived from N.
• Array deployed in Lamont area.
• Automated 24-hr operation
• Data available within 24 hrs.
• Additional GPS-related
deployments in parallel:
SuomiNet, FSL, European group.
NCAR Integrated Sounding System (ISS)
• Profiler, RASS
(mobile?)
• Measures Z, wind
profiles up to a few
kilometers, and T
up to 1 km.
• Launch sondes?
• Near Lamont.
• Automated 24-hr
operation.
• Data available via
Web?
NCAR Surface Flux Facility (ISFF)
• Set of in-situ sensors
making surface (T, wind…)
and flux measurements.
• Nine ISFF requested; no
information on deployment.
• Located where?
• Automated 24-hr
operation.
• Data available via Web?
U. Mass. FM-CW S-band radar
• Very high resolution
vertically pointing radar.
• Makes reflectivity (and
velocity?) measurements.
• No information on
deployment, nor on its
uses. Needs expressed for
ABL and CI work.
• Manned operation; no
information on schedule.
• No real-time data?
• Funding questionable.
Communications and Exchange Issues
• Most instruments are automated and have 24-hr
operation, independent of events  Non issue.
• Only the Raman lidar and the FM-CW radar will
need coordination. I suspect that hours of operation
and mission type, with some weather information, are
all they will need.
• Some could use comparisons with airborne sensors.
• Many can send data; usefulness TBD.
