TWP-ICE/ACTIVE MONSOON CASE STUDY

Retrieved cloud liquid effective radius and ice generalized effective radius (white symbols and lines) versus sample case study simulations (colored lines):





Comments:

• Mean and maximum profiles are calculated for nine 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 six are 24-hour periods: three sequential monsoon events of increasing intensity, followed by cirrus evolution after the third event.
• Tropical Cloud Properties and Heating Rate Profiles (TCPRHP) retrievals at Darwin are supplied by Sally McFarlane, Jim Mather, and Jennifer Comstock. Values represent instantaneous profiles over the DOE ARM site reported at 5-min and 45-m resolution. Non-zero median and maximum values are shown at each level for each time period.
• VISST retrievals near the Darwin ARM site are provided at 4-km pixel resolution by Pat Minnis, derived from MTSAT measurements. We plot all retrievals centered within one degree latitude and within one degree longitude of the Darwin ARM site. Range of non-zero median to maximum values is shown 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 domain-mean values reported at 10-min frequency and 1-km resolution over a domain size of about 37,000 km². Range of non-zero median to maximum values is shown at each level for each time period.

Preliminary summary:

• TCPRHP calculations are for non-precipiting conditions whereas model results include all conditions. Future comparisons will screen model results for non-precipitating conditions and will include the range of instantaneous values produced by the model (rather than the range of domain-mean values shown here).
