MTP Observations During the ATTREX Integration and Test Flight
MTP temperature calibration is excellent and agrees with the MMS calbration (or MMS agrees with MTP, since its calibration was com pleted long before that of MMS!) center dot Having radiosondes laun ched from the Global Hawk base is extremely important for accurate tem pe rature calibration in radiosonde - sparse oceanic regions center. The MTP measurement of the cold-point will make an important contribution to the future ATTREX field campaigns because the demonstrated sp ati al variation of cold- point requires continuous measurements which only the MTP can provide. Profiling with the aircraft is not adequate. The MTP-measured isentropes will be important in studying atmospheric dynamics in the TTL, and how t his dynamics affects both the composition and (possibly) the thermal structure of the TTL.
