| dc.description.abstract | • Evaluated AIRS SAL detection potential given porous radiosonde network (2002–2016) • AIRS vs AIRS/AMSU WML detection rates within 5% • WML: Potent seasonal cycle, best resolved by AIRS • SAL Frequency: Well-matched to observations, WML to SAL conversion rates highest in Sahara (Max 26%) • SAL Properties: • Distinct warm bias (esp. ECMWF) • Layer thickness well captured, but AIRS IQR too small • SAL trajectories: • Precipitation: 43-47% (0-10 mm), 10-13% (100mm+) • Dusty air (> 0.30 ODU): Sahara – 20-22%, Non-Sahara – 40-55% • Caveat: AIRS likely to do better further from rawinsondes station, AIRS results lose little with loss of AMSU. | en_US |
