Short summary

Combining Unmanned Aerial Vehicle (UAV) remote sensing with in-situ monitoring provides high spatial-temporal insights into CO₂ fluxes from temperate peatlands. Dynamic factors (soil temperature and moisture) are the primary drivers contributing to 29 % of the spatial and 43 % of the seasonal variation. UAVs are effective tools for mapping daily soil respiration. CO₂ fluxes from hot spots & moments contribute 20 % and 30 % of total CO₂ fluxes, despite representing only 10 % of the area and time.
