-
-<p><EM>r.evapo.PM</EM> given the vegetation height (hc), humidity (RU),
-wind speed at two meters height (WS), temperature (T), digital terrain model (DEM),
-and net radiation (NSR) raster input maps,

-
-<p>Optionally the user can activate a flag (-z)
-that allows him setting to zero all of the negative evapotranspiration cells;
-in fact these negative values motivated by the condensation of the air water
-vapour content, are sometime undesired because they can produce computational
-problems. The usage of the flag -n detect that the module is run in night hours
-and the appropriate soil heat flux is calculated.
-
-<p>The algorithm implements well known approaches: the hourly Penman-Monteith method as presented in Allen et al. (1998) for land surfaces and the Penman method (Penman, 1948) for water surfaces.<br>
-
-<p>Land and water surfaces are idenfyied by Vh:<br>
-- where Vh>0 vegetation is present and evapotranspiration is calculated;<br>
-- where Vh=0 bare ground is present and evapotranspiration is calculated;<br>

-
-<p>The estimated D raster map (water drained from the vegetation to the groud)
-is calculated for each cell on the basis of the vegetation cover fraction.
-In order to evaluate the total water reaching the groud, and therefore
-available for runoff and infiltration, this quantity should be sommed to
-the rain directly falling to the ground, and eventually to the water
-caming from the snowmelt.
-
-<p>The sum of these three components outputted can be calculated by means
- of teh r.mapcalc command.

+<H2>NOTES</H2>
+
+<p>The estimated D raster map (water drained from the vegetation to the groud)
+is calculated for each cell on the basis of the vegetation cover fraction.
+In order to evaluate the total water reaching the groud, and therefore
+available for runoff and infiltration, this quantity should be sommed to
+the rain directly falling to the ground, and eventually to the water
+caming from the snowmelt.
+
+<p>The sum of these three components outputted can be calculated by means
+ of teh r.mapcalc command.
+<dt>example:
+<br><dd>r.mapcalc 'NETrain = D + (1-Vc)*R + snowmelt';
