Polar Observations and Processes

SHEBA Data Set Acknowledgements

The funding for creating long-term, Arctic, cloud microphysics data sets based on radar data collected at SHEBA was provided by the National Science Foundation's Surface Heat and Energy Budget of the Arctic (SHEBA) Program (Grant# OPP-0084257, Program Managers Mike Ledbetter and Neil Swanberg). The development of the different retrieval techniques that were applied was funded by a number of programs with contributions from the NASA/FIRE Arctic Clouds Experiment (Contract L14997, Project Manager: Victor Delnore), the NASA Earth Observing System Validation Program (Contract S-97895-F, Program Manager: David O'C Starr), and the Department of Energy, Biological and Environmental Sciences Program (Projects ER62342 and ER61960).

The radar was built and operated by the NOAA/Environmental Technology Laboratory with funding from NSF SHEBA Phase I and II monies (Awards OPP-9504254 and Opp-9701730, respectively). The infrared and microwave radiometer data sets were acquired from instruments operated by the Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Program (Director Wanda Ferrell) at SHEBA. The ARM program has data sharing and distribution policies that should be reviewed at http://www.arm.gov, as these cloud retrievals are derived partially from DOE/ARM data sets. Rawinsonde data was collected by the University of Washington.

A large number of individuals have contributed to this project through the development of state-of-the-art instruments, logistics support, retrieval techniques, programming support, discussions, data processing, management of individual input data sets, and idea generation. In particular, the inputs of the following individuals are recognized: Jeff Otten, Bruce Weilicki, Judy Curry, Matthew Shupe, Sergey Matrosov, Shelby Frisch, Janet Intrieri, Eugene Clothiaux, Patrick Minnis, Bill Rossow, Louis Nguyen, Ken Moran, Ann Keane, Duane Hazen, Brad Orr, and Paquita Zuidema. The data collected during SHEBA would not have been possible without the outstanding support from the captains and crews of the Canadian Coast Guard Ships Des Groseilliers and Louis St. Laurent, and the Applied Physics Laboratory at the University of Washington.
