The annual energy budgets of four small ponds in northwestern Florida were calculated from the amounts of 1) solar radiation, 2) atmospheric long—wave radiation, 3) back radiation, 4) evaporative energy, 5) conducted energy, and 6) sensible heat which entered or was lost from the wager. Long—wave radiation constituted between 62.1 and 63.9% of the total incoming radiative energy and 80.8 to 85.0% of the total energy loss. Evaporative loss was between 14.6 and 18.3% of the total. Between 370,498 and 631,970 kcal m ( —2)yr ( —1) (37,050 — 63,197 cal cm ( —2)y ( —1)) were stored. Atmospheric radiation counteracts a portion of the radiative loss from water, thus reducing loss of stored solar energy.
