PeatlandN<sub>2<\/sub>O will calibrate the model with N<sub>2<\/sub>O flux measurements in the project study sites. As input, the model will use synchronous and continuous high-frequency measurements and remote sensing of proxy environmental parameters, most importantly soil moisture, soil temperature, and vegetation characteristics. The model will be validated against published ground measurements from peatlands worldwide. Based on existing spatial datasets, a statistical approach will be used, including, most relevantly, soil moisture, soil temperature, vegetation, land use and fertilisation gridded data sets.\n<\/p>\n<p>\n\t<img loading=\"lazy\" decoding=\"async\" width=\"1325\" height=\"768\" class=\"alignnone wp-image-50\" src=\"https:\/\/sisu.ut.ee\/wp-content\/uploads\/sites\/659\/fig5.png\" title=\"fig5.png\" alt=\"model\" srcset=\"https:\/\/sisu.ut.ee\/wp-content\/uploads\/sites\/659\/fig5.png 1325w, https:\/\/sisu.ut.ee\/wp-content\/uploads\/sites\/659\/fig5-300x174.png 300w, https:\/\/sisu.ut.ee\/wp-content\/uploads\/sites\/659\/fig5-1024x594.png 1024w, https:\/\/sisu.ut.ee\/wp-content\/uploads\/sites\/659\/fig5-768x445.png 768w\" sizes=\"auto, (max-width: 1325px) 100vw, 1325px\">\n<\/p>\n<p style=\"text-align: center\">\n\t<i>Conceptual scheme of the PEATN2O model coupling the process-based N<sub>2<\/sub>O and GIS-based regional\/global N<sub>2<\/sub>O submodels<\/i><\/p>\n","protected":false},"excerpt":{"rendered":"<p>PeatlandN2O will develop the two-level PEATN2O model of N2O fluxes.
