That energy can be measured using instruments that are sensitive to energy in this portion of the electromagnetic spectrum. Well-established algorithms are then used to convert these TIR values to surface temperature, incorporating some knowledge of emissivity, a factor that varies with physical parameters such as material composition, moisture content, roughness and pore space. <\/p>\n\n\n\n<p>In the early morning (pre-dawn), there is little influence of solar radiation on the surface and the energy can be attributed to coming from either an internal heat source (geothermal) or to the emission of energy absorbed by the surface the previous day (natural). At solar noon, the surface will have reached the maximum heating from the sun and, where topographic shadow is not present, the amplitude between these pre-dawn and solar noon measurements provides an indication of the differential heating of a surface as a function of its variable thermal properties. This technique is limited in application where vegetation masks the surface.<\/p>\n\n\n\n<p>BGS Geodesy and Earth Observation provides expertise on thermal assessment of land surfaces. The thermal imagery that we process and interpret is obtained from satellite or airborne instrumentation, or we acquired it using drone platforms. <\/p>\n\n\n<figure  class=\"img-wrap\"><a href=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/02\/Thermal_IR_field_work.jpg\" data-toggle=\"lightbox\" data-footer=\"&lt;p&gt;The thermal drone survey team warming up after early morning fieldwork in Los Humeros.
