This data set is derived from measurements collected in situ by the NASA DC8 during the Tropical Cloud Climate Composition Coupling Experiment (TC4) that was conducted during July and August, 2007 (Toon et al., 2010). During this experiment the DC8 was based in San Jose, Costa Rica and sampled clouds in the maritime region of the Eastern Pacific and adjoining continental areas. The primary objective of the DC8 during this deployment was to sample ice clouds associated with convective activity. While the vast majority of the data are from ice-phase clouds that have recent association with convection, other types of clouds such as boundary layer clouds and active convection were also sampled and are represented in this data set. The derived data set, as compiled in this delivery, includes approximately 15,000 5-second averaged measurements collected by the NASA DC8.

Purpose

The main purpose of this dataset is to utilize existing in situ data to better characterize uncertainties in the retrieval of cloud and precipitation microphysical properties using ground- and space-based remote sensing data and to determine if certain combinations of frequencies and radar-measureable quantities provide information beyond what might be known simply from airborne climatologies.
