a Remote sensing-based relationships between mean temperature sensitivities (\({{{{\rm{\delta }}}}{{{\rm{Ts}}}}}^{{{{\rm{bph}}}}}\) and \({{{{\rm{\delta }}}}{{{\rm{Ta}}}}}^{{{{\rm{bph}}}}}\)) and background shortwave radiation (SWd). The boxplots show the monthly temperature sensitivities within the corresponding SWd interval. The boxes indicate the interquartile range; the whiskers indicate the data range (5th and 95th percentiles); the lines and dots inside the boxes are the medians and means, respectively. b FLUXNET-based relationships between the mean temperature sensitivities (\({{{{\rm{\delta }}}}{{{\rm{Ts}}}}}^{{{{\rm{bph}}}}*}\) and \({{{{\rm{\delta }}}}{{{\rm{Ta}}}}}^{{{{\rm{bph}}}}*}\)) and SWd. The shaded area indicates the standard error for the mean sensitivity within each SWd bin. c Same as (a), but for the maximum temperature sensitivities derived from remote sensing data (\({{{\rm{\delta }}}}{{{{\rm{Ts}}}}}_{\max }^{{{{\rm{bph}}}}}\) and \({{{\rm{\delta }}}}{{{{\rm{Ta}}}}}_{\max }^{{{{\rm{bph}}}}}\)). d Same as (b), but for the maximum temperature sensitivities from FLUXNET measurements (\({{{\rm{\delta }}}}{{{{\rm{Ts}}}}}_{\max }^{{{{\rm{bph}}}}*}\) and \({{{\rm{\delta }}}}{{{{\rm{Ta}}}}}_{\max }^{{{{\rm{bph}}}}*}\)). Here, Climatic Research Unit (CRU) temperature data are used to exclude the impact of macroclimate background in FLUXNET temperature measurements.
