This project’s aim is to develop an Accurate Active Light Source (AALS) that can be fielded at selected calibration sites to address NOAA’s unmet needs and improve the calibration of the Suomi NPP VIIRS Day Night Band (DNB) operating in the high gain stage (HGS) under low light level conditions. The DNB HGS has extreme low-light sensitivity that enables a new generation of nighttime imaging. M ...

Most sensor data collection systems are unique to a given application, sensors do not easily transcend across applications or platforms. Smart sensor development improved the ability to utilize common communications to a certain degree, where most used RS-232 or RS-485 type communications protocols, but differences are still found and no uniformity exists in the commercial markets. The Smart Modul ...

Current research shows that failures in the standardization process are often the result of a failure of the participants to communicate or organize. To this effect, NIST has developed a tool, NIST Ontological Visualization Interface for Standards (NOVIS), with an environment for visualizing, browsing, and querying standards. Aztera will create a Computer Aided Standards Development (CASD) framewo ...

A new radiometric vicarious calibration approach for the Suomi NPP VIIRS Day/Night Band’s (DNB) high gain stage (HGS) is proposed that will complement traditional, extended source, radiance-based calibrations, which are based on natural lunar illumination and not as accurate as desired. The proposed research will produce affordable, field-deployable, NIST-traceable point source lamps that can ac ...
