TL;DR: In this paper, field measurements of ground truth were made over bare soil in addition to green grass, alfalfa and corn, at an agricultural research site in Spain during two coincident campaigns (SPectrA Barrax Campaign, or SPARC, and Exploitation of AnGular effects in Land surface, or EAGLE) during an ASTER overflight.

TL;DR: In this paper, a description of thermal radiometric field measurements carried out in the framework of the European project SENtinel-2 and Fluorescence Experiment (SEN2FLEX) is presented.

TL;DR: In this paper, a simple linear mixing of pixel elements (subpixels) was used to examine the impacts of pixel mixtures on temperature retrieval and ground leaving radiance, and the results showed that for a single material with one temperature distribution and with a subpixel temperature standard deviation of 6-k (daytime images), the effects of subpixels temperature variability are small but can exceed 0.5-k in the 3-5-µm band and about a third of that in the 8-12-m band.

TL;DR: In this article, a modified version of the normalized emissivity method (NEM), utilizing independently scaled maximum emissivities in each channel, was applied to thermal data acquired by the Multispectral Thermal Imager (MTI) with two MIR channels, J (3.81 μm) and K (4.97 μm).

TL;DR: The results indicate that, with the exception of band L, the instrument measured radiances are warmer than expected and the absolute radiometric accuracy of the MTI data acquired in bands J-N was assessed over a period of approximately three years.
