# Infrared heat imaging data ## Summary Infrared heat imaging data is collected collected using the FLIR SC615 thermal sensor. These data are provided as geotiff image raster files as well as plot level means. * Algorithms are in the [flir2tif directory of the Multispectral extractor](https://github.com/terraref/extractors-multispectral/tree/master/flir2tif) repository; see the readme for details. * Sensor information: [FLIR Thermal Camera collection](https://terraref.ncsa.illinois.edu/clowder/datasets/5873a7184f0cad7d8131994a) ## Level 1 Data Access ### Filesystem (Globus and Workbench) * `ua-mac/Level_1/ir_geotiff` ### Clowder To be created ## Level 3 Data Plot level summaries are named ['surface\_temperature'](http://mmisw.org/ont/cf/parameter/surface_temperature) in the trait database. In the future this name will be used for the Level 1 data as well. This name from the Climate Forecast (CF) conventions, and is used instead of 'canopy\_temperature' for two reasons: First, because we do not (currently) filter soil in this pipeline. Second, because the CF definition of surface\_temperature distinguishes the surface from the medium: "The surface temperature is the temperature at the interface, not the bulk temperature of the medium above or below." ## Raw data access Thermal imaging data is available via Clowder and Globus: `/ua-mac/raw_data/flirIrCamera` For details about using this data via Clowder or Globus, please see [Data Access](https://github.com/terraref/documentation/tree/56f669dc870b3c3921bfc029914545574e70f8df/how-to-access-data.md) section. ## Known Issues * Data are unavailable for Season 4 (summer 2017 sorghum) and season 5 (winter 2017-2018 wheat). * Work to recover these data is ongoing; see [terraref/reference-data#190](https://github.com/terraref/reference-data/issues/190) * Problem description [terraref/reference-data#182](https://github.com/terraref/reference-data/issues/182) ## See also * [Geospatial information](/user-manual/data-products/geospatial-information.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.terraref.org/user-manual/data-products/infrared-heat-imaging-data.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
