The CEPEX Integrated Data System (CIDS) was developed by the Center
for Clouds, Chemistry and Climate (C^4) at Scripps Institution of
Oceanography (SIO). The system provides easy and uniform access to
all of the observations from the Central Equatorial Pacific Experiment ... (CEPEX) conducted in March and April, 1993. CEPEX was designed to
address two primary scientific issues: (1) why are maximum sea surface
temperatures (SSTs) in the tropical oceans so close to the 300K
threshold for deep convection?, and (2), what are the restoring forces
that limit SST and deep convection? CIDS is designed to facilitate
multidisciplinary research by providing a common interface to complex
and heterogeneous data sets.
CIDS data sets include observations atmospheric and ocean parameters
from multiple platforms such as: NOAA polar orbiting satellites
(NOAA-11 and NOAA-12), Defense Mapping Satellite Program (DMSP) polar
orbiters, and Japan's GMS-4 geostationary satellite. Aircraft
observations were from NASA's ER-2, the Learjet from Aeromet, Inc.,
NOAA's P-3, and NCAR's Electra. Ocean observations were taken from
the Research vessel Vickers operated by NOAA and the University of
Southern California (USC), TOGA-TAO buoy moorings, upper air sounding
stations, ISS and wind profilers.
CIDS data sets include:
- Solar and long-wave radiation fluxes and satellite radiation budget at
the sea surface and at altitudes corresponding to tropopause, cirrus
anvil top and base, and top of the boundary layer.
- SST measurements from Vickers and vertical profiles of temperature and
winds from sea surface to about 25 km from Vickers, Learjet dropsondes
and soundings from CEPEX islands, ISS stations and the GTS-UPA
- Water vapor concentrations from the sea surface to about 25 km and
their diurnal variations.
- Evaporative and sensible heat fluxes from the sea surface from Vickers
and TOGA-TAO moorings plus near surface fluxes from boundary missions
with P-3 and Electra aircraft.
- Size distribution of ice crystals, particle shape at cloud-base and
cloud-top altitudes as measured by Learjet from -30C level to its
- Cloud-top and cloud-base altitudes from ship and aircraft radar and
from the ER-2 lidar.
- Ozone measured from the surface to about 25 km on upsondes from the
Vickers and 18 km altitude ozone from ER-2.
- Modeled velocity, temperature and pressure fields from ECMWF and NMC.
