Physical and chemical oceanographic data collected aboard NOAA Ship RONALD H BROWN during the Joint Air-Sea Monsoon Interaction Experiment (JASMINE) in the Indian Ocean, Bay of Bengal, and the Timor Sea from 1999-04-10 to 1999-06-06 (NCEI Accession 0001029)

Observations made during the field phase of JASMINE sampled both prolonged break and active phases of the monsoon resulting in an unprecedented amount of research quality data defining the atmospheric and oceanic state during intra-seasonal transitions of the monsoon. The design of the JASMINE pilot study was based on the observation that the intra-seasonal variability of the monsoon, as it sways back and forth from active to inactive (or break) phases, is an important component of the monsoon system and one that is poorly sampled and simulated.
