Tethered Atmospheric Observation System (TAOS) Data [NCAR/EOL]



The Tethered Atmospheric Observing System (TAOS) used during the IHOP project was located one mile east of the Homestead site, on the south side of the road (Lat 36 deg 33.500 min N, Lon 100 deg 36.371 min W, Alt 850m). The tethered system is comprised of up to eight NCAR designed and built sensor platforms using the Vaisala RS-90 P, T and RH sensor package for these measurements. Wind speed comes from an R.M. Young propellor using an optical chopper. Wind direction comes from a Honeywell magnetometer which provides pitch and roll information in addition to direction. The sensor packages are tethered to a large balloon, and are spaced apart at various altitudes along a line attached to the balloon. Each transmits one second resolution data simultaneously over a period of time. The IHOP TAOS datasets were collected on June 12, 14 and 21 of 2002.
