Original publisher: Greenbelt, Md. : National Aeronautics and Space Administration, Goddard Space Flight Center, [2000] OCLC Number: (OCoLC)66460698 Excerpt: ... 27 May 1994 4.3 Flight Hours ( Hobbs ) Pilot: TLC SUMMARY: Two site specific runs-asterisks over the Black Spruce Tower, then one over the Old Jack Pine tower. CO2 sensor was calibrated prior to flight. WEATHER: On Takeoff, clear wx conditions-haze to East no clouds directly above, thin high stratus. Basically clear all day, with stratus building and coming in from the west at about 2000Z-50 %, from morning of about 15 %. Note: BS not a good place for a site specific-there is a lot of heterogeneity: lot of little lakes, lot of chopped up stuff-lot of terrain-looking for the best direction that offers a good comparison with the tower. OJP coordinated from Piers 53.916N, 104.69W. TAKEOFF: 1630Z FSS Temp 22 C LANDING: 2030 NOTES: On ground met readings prior to takeoff: T = 21.6 C, Tw = 15.2 C, P = 954.7 mb After flight met readings: T = 28 C, Tw = 15.4 C, P = 952.4 29 May 1994 Flight hours 2.8 ( Hobbs ) Pilot: TLC SUMMARY: An OJP site asterisk plan was flown. In conjunction, the Twin Otter was flying an " L " pattern across all tower sites, and the NASA helicopter took measurements in the same area. CO2 IRGA calibration was done prior to flight, so there is an updated zero and span available. Additionally, the probe temperature sensor was changed from the glass microbead to the wire microbead; therefore, the zero and span of the temperature probe has changed. WEATHER: Overcast most of the day. At P.A.: cloud est to be 3200 Sct, 9000Bkn, 25000 Bkn, vis 15 miles. It was more cloudy to the southwest when over the site. At landing, a system had moved in from the south, and iite precipitation had begun. TAKEOFF: 1740Z LANDING: 2020Z NOTES: The date and time were set incorrectly, so the first file has the wrong time. The GPS reset the time when the file was closed, he date had been 27 May, ( edited after the ...
