This experiment will be flown during the Fall 1995 mission.
The upper troposphere Egrett will be used as an above cloud platform and the DH-6 as a lower troposphere, below cloud platform. The mission of these aircraft is to provide measurements of net fluxes at 12 km and 0.8 km MSL, respectively, in both cloudy and clear sky conditions. These two aircraft have good speed coordination and will fly in coordination with their horizontal distance ideally not exceeding 2 km.The ER-2 will be flying at the tropopause at a much higher speed. It will mainly be used to calibrate retrievals used to convert the satellite radiance data to TOA upwelling broadband fluxes. The ER-2 RAMS flux measurements will be particularly valuable when it momentarily overflies the Egrett -- DHC-6 stack.
(the ARESE Flight Track figure is unavailable)
On any given flight day all aircraft will fly one of three standard tracks shown [sic] in the accompanying figure (one of the two long legs or the triangle), with the particular one selected the previous evening based on forecast cloud and upper tropopause wind conditions as well as on instrument readiness and satellite calibration opportunities. The wind conditions affect the ability of the Egrett and DHC-6 to maintain coordinated flight. All three tracks overfly the CART central facility and selected extended facilities to insure periodic stacking of measurement assets in a column. The track for the ER-2 may be extended to avoid an undesirable turning frequency.
The 10 km full width flight corridors associated with all three of these tracks as well as 20 km diameter turning circles are shown [sic] in the figure. These corridors provide safe operating margins and represent regions for which flight approval will be sought. They have been chosen to avoid as much as possible overflight of small cities and towns in the area.
The first flight track is a triangle with vertices at the CART central facility (Lamont SIROS), and at the Ringwood and Byron extended facilities where the zenith RAMS are located. The flight path lengths are (beginning with the central facility and heading toward Ringwood, including the dogleg) 75 km, 50 km, and 78 km.
The second flight track is near linear between the central facility and the Coldwater extended facility, flying over the Byron site along the way. The flight path including a slight bend is 182 km long in the WNW - ESE direction.
The third flight track is also near linear between the central facility and the Vici extended facility, flying over the Ringwood site along the way. The flight path including two slight bends is 163 km long in the WSW - ENE direction.
The ER-2 flight operations must optimize calibration of satellite GOES and NOAA retrieval algorithms for broadband flux as spelled out in the separate ARESE science plan.
The ARESE science team's operation center will be collocated with the ARM-UAV operations center at the Blackwell Tonkawa Airport.
