Dr. Charles N. (Chuck) Long
Dr. Charles N. Long specializes in the study of clouds and their effect on the surface radiation energy balance of the Earth-atmosphere system. His research interests include observation, quantification, and analyses of the surface radiative energy budget, quantification of cloud macro-physical properties from surface-based measurements, and cloud forcing and feedbacks with respect to surface radiation. Toward these ends, he has developed a widely used algorithm for automated quality assessment of surface radiation budget data (e.g. the QCRad code currently used by several surface radiation networks), and pioneered the development of techniques to infer cloud properties using surface radiometer and meteorological measurements. These techniques are applied to available surface measurements to assess climatological statistics and trend detection related to climate change. These methodologies and algorithms thus maximize the quality of basic and retrieved products from BSRN-type surface radiation measurement systems, and produce value-added parameters that increase the value of surface radiation measurements well beyond the measurements themselves. Other areas of interest include the development of surface-based instrumentation and systems for measuring cloud and radiative properties, and observational field campaigns, where Dr. Long has a long history of participation and leadership.
Dr. Long was awarded the 2000 Professor Dr. Vilho Vaisala Award in Atmospheric Sciences by the World Meteorological Organization in recognition of a collaborative paper, “Ground-based Remote Sensor Observations during PROBE in the Tropical Western Pacific,” published in the February 1999 issue of the Bulletin of the American Meteorological Society; and again awarded the 2012 Professor Dr. Vilho Vaisala Award in Atmospheric Sciences in recognition of the collaborative paper “Optimized fractional cloudiness determination from five ground-based remote sensing techniques,” published in the December 2010 issue of the Journal of Geophysical Research. Dr. Long is to date the only two-time winner of the Vaisala Award in Atmospheric Sciences. Dr. Long participates in national and international committees, boards, and advisory groups. He was recently appointed to the International Radiation Commission (IRC) Global Energy Balance Working Group and is on the Editorial Advisory Boards of The Open Atmospheric Science Journal and The Open Ocean Engineering Journal. He currently serves as the World Meteorological Organization’s (WMO) international Baseline Surface Radiation Network (BSRN) Project Manager. He is an invited co-author for the WMO Global Energy and Water Cycle Experiment (GEWEX) Radiative Flux Assessment chapter on surface observations and an invited member of the IASOA (International Arctic Systems for Observing the Atmosphere) Surface Radiation Balance Working Group.
