General Description

IHOP 2002
The International H2O Project
(IHOP 2002)
is a field experiment scheduled to take place over the Southern Great Plains (SGP) of the United States from 13
May to 25 June 2002. The chief aim of IHOP 2002 is improved characterization of the four-dimensional (4-D) distribution of water vapor and its application to improving the understanding and prediction of
convection. The region is an optimal location due to existing experimental and operational facilities, strong variability in moisture, and active convection.

Campaign Highlights
|
May 14 - June 25, 2002
Homestead Profiling Site, OK
GLOW operations during IHOP
>270 hours of wind profiles obtained in 34 days of operations.
Coincident operation with HARLIE, SRL, Aeribago, ISS profiler and sondes.
Transmitted laser energy, effective telescope aperture, elevation angle varied to optimize operations for altitudes <5 km.
Wind speed and direction derived from LOS winds measured at 4
azimuth angles (0,90,180,270 deg) and elevations of 15,30,45 degrees.
RHI, PPI scans also taken for specific events

Objectives
|
Primary
-Continuous times series of wind speed and direction from the surface to the tropopause
--Characterize flow and dynamics in and above the BL
--Unique data product in the IHOP measurement suite: compliments profilers, dropsondes
-Combine GLOW data with co-located lidars
--SRL observations of H2O
--HARLIE observations of winds and PBL structure
Secondary
-Intercompare with other wind profilers in overlapping altitude regions
-Aerosol profiling of PBL winds
