Comments:Science flight for the HU-25 in support of ACTIVATE Campaign #3, conducted cooperatively with the UC-12. Departed Rwy08 to ATLIC climbing to 3k ft MSL for initial transit. Research profiles conducted from KLFI-ATLIC-ZIBUT-3730N/07136-3612N/07113.2W-3436N/07045.6W-3652.8N/07125.2W-ATUGI-ZIBUT-ATLIC-KLFI. Winds were light (<15 knots) and variable (120-210) at flight altitudes with a scattered offshore layer initially encountered from ~3-4 k FT MSL (ATLIC-ZIBUT), followed by a clear section approaching ZIBUT before re-entering layers transiting to first Lat/Long. Tuned approximately 10 nmi early on return leg to ZIBUT in order to remain within cloud layer. Both cloud and clear air modules were completed throughout the flight as conditions warranted, ranging from 500 – 5500 FT MSL. A temperature inversion was noted from ~2500-5500 with a transition from ~4deg C to ~12 deg C, respectively. Synchronized with CALIPSO overpass just beyond the second Lat/Long position. Aircraft geolocation was within ~5 nmi throughout the flight. All objectives were achieved and no system discrepancies were noted - pending post-flight data analysis.
