TWP-ICE/ACTIVE MONSOON CASE STUDY
Surface sensible and latent heat fluxes from measurements and ECMWF (white symbols) versus sample case study simulations (colored lines):
Comments:
- Forcing data set derived from variational analysis over the TWP-ICE domain bounded by sounding sites, provided by Shaocheng Xie and Minghua Zhang (summary with download link), reported as 3-hr mean values over the area of approximately 25,000 km2.
- Eddy covariance measurements from the TWP-ICE Darwin harbor site (instrumentation mounted on a short tower in central harbor waters) are provided by Jason Beringer. Each point represents a 30-minute average.
- Large-scale forcing data are derived from variational analysis by Shaoecheng Xie and Minghua Zhang. Surface PR represents 3-hr mean values over an area of approximately 25,000 km2.
- ECMWF supplies hourly mean data at 0.56x0.56-degree resolution, from which mean values are plotted over the three grid boxes centered nearest to and immediately west of the Darwin ARM site, representing a total area of approximately 11,500 km2.
- 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 from 1-km resolution over a domain size of about 37,000 km2. Mean values shown at each level for each time period.
- The forcing data represent an average over the TWP-ICE domain (part ocean, part land), with a strong diurnal signal, whereas the harbor flux measurement site and the simulations exhibit little such signal. The ECMWF results represent three grid boxes near Darwin, one of which is oceanic and resembles the marine site and the idealized marine model results.
