Infrared reflectography of paintings is used to make underlying layers clearly visible in contrast. IR radiation penetrates the upper layers of the painting and is reflected by the primer. The underdrawing, which is made with carbonaceous colorants on the primer, absorbs IR radiation and shows a strong contrast. The 2 MP sensor of the camera in combination with a lens with a short minimum working distance allows the realization of a very high resolution, which is important for the possibility to evaluate the underdrawing. The effective achievable resolution is therefore dependent on both components, sensor and lens.

This is the AmeriFlux Management Project (AMP) created FLUXNET-1F version of the carbon flux data for the site US-Tw5 East Pond Wetland. This is the FLUXNET version of the carbon flux data for the site US-Tw5 East Pond Wetland produced by applying the standard ONEFlux (1F) software. Site Description - The Twitchell Wetland site is a 6.5 acre restored wetland on Twitchell Island, that is managed by the California Department of Water Resources (DWR) and the U.S. Geological Survey (USGS). In the fall of 1997, the site was permanently flooded to a depth of approximately 55 cm. The wetland remained fairly unvegetated in patches increasing in size towards the east. The site underwent a major disturbance in 2013 when the vegetation was removed to seed a nearby restored wetland. A flux tower equipped to analyze energy, H2O, CO2, and CH4 fluxes was installed on April 17, 2018.
