TWP-ICE/ACTIVE MONSOON CASE STUDY

Radiative heating rate profile retrievals (white symbols) versus sample case study simulations (colored symbols):



Comments:

• Mean profiles are calculated for six time ranges. The first three are longer time ranges: (1) all times following an initial 36 hours for model spin-up, (2) six days of monsoon, and (3) six days of suppressed conditions. The second three are sequential monsoon events of varying intensity.
• Tropical Cloud Properties and Heating Rate Profiles (TCPRHP) retrievals at Darwin are supplied by Sally McFarlane and Jim Mather. Values represent instantaneous profiles over the DOE ARM site reported at 5-min and 45-m resolution when surface precipitation is < thresholds. Mean and maximum values are taken here at each level for each time period.
• All measurement data have been downloaded from the DOE ARM data archive (www.arm.gov) and use in publications is subject to the policies described there. Any errors in plotting or representation shown here should be blamed on Ann Fridlind.
• Model results are instantaneous values reported at 3-hr frequency and 1-km resolution over a domain size of about 37,000 km². Mean values are shown at each level for each time period.

Preliminary summary:

• Retrievals are for non-precipiting conditions whereas model results include all conditions. Future comparisons will screen model results for non-precipitating conditions and will include separate comparison of SW and LW components.
