IHOP Operations Plan, Chapter 7:

Other Special Ground-Based Instrumentation

Operation“Other special instruments” are non-mobile and non-scanning radar sensors. Two broad categories:

• Water vapor remote sensors: Lidars, radiometers, GPS.

• Support instruments:Profiler, flux towers, FM-CW radar.

Other Special Ground-Based Instrumentation

OperationExcept 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.
