IHOP Operations Plan, Chapter 7: Other Special Ground-Based Instrumentation Operation • General overview • Instrument deployment and specific issues • Information exchange and coordination Frédéric Fabry et al.
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 ~5 x 5 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: Suomi. Net, 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.
