Helicopter Observation Platform (HOP)
STATUS
Under Development
AVAILABILITY
no limits, except when already committed to field campaigns. Current commitments include CHATS (April-May 2007), CLASIC (June 2007), and Savannah River Lab (exact dates TBD).
REQUEST PROCEDURE
contact Professor Roni Avissar at: ravissar@rsmas.miami.edu 305.421.4000
Airborne Platforms
HOP is based on a Bell JetRanger 206B3 with a total available payload for scientific instruments of ~500 lbs (fully fueled with pilot and co-pilot allowing for uninterrupted flight time of up to 3.5 hours). It is currently equipped with a 3D sonic anemometer developed by Kaijo for aircraft operation, with an AIMMS-20 produced by Aventech and upgraded for measurements of high-frequency temperature, and with a Licor 7500. Thus, HOP is well equipped to measure momentum, sensible, latent and CO2 turbulent fluxes by eddy correlation. A lidar is being constructed and will be mounted on the HOP in July 2007. HOP is modular so that equipment can be mounted for a specific field experiment.
