The funding for creating long-term, Arctic, cloud microphysical data sets was provided by the NASA Earth Observing Validation Program (Contract S-97895-F, Program Manager: David O'C Starr). The development of the different retrieval techniques that were applied were funded by a number of programs with contributions from the NASA/FIRE Arctic Clouds Experiment (Contract L14997, Project Manager: Victor Delnore), the NSF Surface Heat and Energy Budget of the Arctic (SHEBA) Program (Grant # OPP-0084257, Program Managers Mike Ledbetter and Neil Swanberg) and the Department of Energy, Biological and Environmental Sciences Program (Projects ER62342, ER61960 and ER63965)
The radar, radiometer, and rawinsonde data sets were acquired from the Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Program (Director Wanda Ferrell) data archives, and were collected by instruments that are operated as part of the North Slope of Alaska operations of the DOE/ARM program. The ARM program has data sharing and distribution policies that should be reviewed at http://www.arm.gov as these cloud retreivals are derived completely from DOE/ARM data sets.
A large number of individuals have contibuted to this project through development of state-of-the-art instruments, retrieval techniques, programming support, discussions, data processing, managment of individual input data sets, and idea generation. In particular, the inputs of the following individuals are recognized: Bruce Weilicki, Matthew Shupe, Sergey Matrosov, Shelby Frisch, Eugene Clothiaux, Patrick Minnis, Bill Rossow, Louis Nguyen, Ken Moran, Ann Keane, Duane Hazen, Brad Orr, and Paquita Zuidema. Appreciation is extended to the DOE/ARM, in particular Kevin Widener, Mark Miller and Jim Liljegren.
The work described here was performed by the NOAA/ESRL Physical Sciences Laboratory. Comments, questions and suggestions should be directed to Taneil Uttal.
