Fig. 4: Measured mean monthly latent heat flux (LE) or Evapotranspiration (ET) by the eddy covariance method and specific humidity (q) for all 20 urban sites worldwide.
From: Urbanization alters atmospheric dryness through land evapotranspiration
a Significant correlations between LE versus q for Δq < 0 and Δq ≥ 0, respectively. b Correlation coefficient of LE versus q for individual sites. All the 20 sites passed Two-tailed T-test at the significance level of 0.001. The names and locations of the 20 sites are in Fig. 1a and Supplementary Table 1. Δq was calculated using data from 20 urban sites published in https://doi.org/10.5281/zenodo.710498459, and surrounding pixel data from ERA5 as non-urban areas, respectively. LE and q data were monthly data (n = 621) from 20 urban flux sites (2003–2020).
