The South China Sea Monsoon Experiment (SCSMEX) was an international experiment designed to understand the key physical processes for the onset, maintenance and variability of the Southeast Asian monsoon. The field phase of SCSMEX was held from 1 May to 30 June 1998 during which two Intensive Observing Periods (IOPs) were conducted. During these IOPs extensive meteorological and oceanographic observations were taken over the South China Sea. An integral part of observational network during the IOPs included: two research vessels (Shiyan 3 located near 20N, 117E and Kexue 1 near 6N, 110E), which took high resolution vertical soundings of the atmosphere and detailed surface measurements, and a network of two Doppler radars in the northern South China Sea.

Colorado State University participated in the SCSMEX field program principally through the collection of atmospheric sounding data (PI: Prof. Richard H. Johnson, CSU) and surface data collected on the ships (PI: Dr. David Parsons, NCAR ATD). Our future work will be to provide a research quality atmospheric gridded dataset over the SCMSEX domain for May and June 1998.

We caution that the gridded data are PRELIMINARY, having been subjected to only minimal quality control. Work is continuing on a second version with more extensive quality control, higher time resolution and other improvements. However, even further improvements are anticipated in 1999 and beyond in connection with ongoing sounding data collection activities by the Beijing data center, UCAR, and the GAME community. as well as proposed quality control efforts by UCAR. To keep abreast of analyses updates, we encourage users to register your use of the datasets with us (see contact person at bottom of this page).
