NASA Remote Sensing Flight Validation Planning Andy Reehorst NASA Glenn Research Center
Status • NASA is defining a new flight campaign to support Icing Remote Sensing. • NASA’s Icing Remote Sensing activity needs detailed, accurate in-situ data for development/calibration/validation of ground-based systems. • Our Remote Sensing needs can be satisfied with a limited duration flight test with the NASA Twin Otter • NASA Aviation Safety Program has elevated the flight test milestone from a Level 1 to an Annual Performance Indicator (API, formerly APG).
Twin Otter Test Scope • Plans include operations from and in the area of Cleveland Hopkins airport (CLE). • NASA GRC is located at CLE • CLE has an updated (dual polarization) NEXRAD system • Instrumentation needs satisfied by AIRS II-type equipage. • Building up an updated suite of similar instruments • Require: LWC, droplet sizing spectra , temperature, humidity, 4-D position/time • Flight maneuvers will likely include: • Terminal area transects (constant heading/altitude overhead passes at multiple altitudes) • Climbing or descending spirals • Missed approach (low altitude) passes. • Winter FY15 flights • Exact number of flight hours and dates are YTBD • Green API status requires “5 weather events”

Possible Collaboration • Canadian NRC is also hoping for an Ontario-based flight test with their Convair next winter. If they have funding, they would like to make some flights over CLE. • Remote Sensing onboard • NRC W and X band • NRC and EC cloud lidar • Cloud micro physics • FSSP (2) • CDP (2) • 2DC • CIP • 2DP • Korolev extinction meter • Rosemount ice detector • Nevzorov • King • Atmospheric State • AIMMS-20 • Rosemount 858 • OAT (2) • LiCor • Edgetech Hygrometer
