Data sets

Energy and carbon dioxide fluxes, meteorology and soil physics observed at INCOMPASS land surface stations in India, 2016 to 2017 R. Morrison, S. S. Angadi, H. M. Cooper, J. G. Evans, G. Rees, M. Sekhar, C. Taylor, S. N. Tripathi, and A. G. Turner

Short summary
Transpiration fluxes by vegetation are reduced under heat stress to conserve water. However, in situ observations over northern India show that the strength of the inverse association between transpiration and atmospheric vapor pressure deficit is weakening in the presence of heavy aerosol loading. This finding not only implicates the significant role of aerosols in modifying the evaporative fraction (EF) but also warrants an in-depth analysis of the aerosol–plant–temperature–EF continuum.
