<abstract>
<p>This paper introduces a method for recovering global fields of
near-surface net available energy (the sum of the sensible and latent
heat flux or the difference between the net radiation and surface heat
accumulation) using satellite visible and infra-red products derived
from the AIRS (Atmospheric Infrared Sounder) and MODIS (MOderate
Resolution Imaging Spectroradiometer) platforms. The method focuses on
first specifying net surface radiation by considering its various
shortwave and longwave components. This was then used in a surface
energy balance equation in conjunction with satellite day-night
surface temperature difference to derive 12 h discrete time estimates
of surface system heat capacity and heat accumulation, leading
directly to a retrieval for surface net available energy. Both net
radiation and net available energy estimates were evaluated against
ground truth data taken from 30 terrestrial tower sites affiliated to
the FLUXNET network covering 7 different biome classes. This revealed
a relatively good agreement between the satellite and tower data, with
a pooled root mean square deviation of 98 and 72 W m&lt;sup&gt;−2&lt;/sup&gt; for net
radiation and net available energy, respectively, with little bias
particularly for the net available energy.</p>
