David B. Pollock, an associate research professor and senior research scientist in the UAH Electrical and Computer Engineering Department and Optics Department, is a contributing author to the newest edition of a National Institute of Standards and Technology (NIST) Handbook, "Guidelines for Radiometric Calibration of Electro-Optical Instruments for Remote Sensing." Under development since 2012, this new handbook is a national level publication intended to provide guidelines for the radiometric calibration of imaging, spectral-imaging, narrow and broadband radiometers built by the aerospace industry, universities, and national laboratories. This NIST handbook is intended to be a reference for managers, technical oversight personnel, scientists and engineers to assure sensor calibrations are successful. Success begins with planning and continues throughout a sensor operational lifetime. Sensor applications are broadly based; the handbook is applicable to sensors on-board satellite, aircraft and balloon platforms.
