You can go to the the respective categories to check about available AMLs. A short descriprion is given. You can click on the AML-name to get a more detailed dicussion and a brief manual. At the same location you can download the AMLs if you like to.
| 1.1 shortwave.aml | Original code of L. Kumar’s routine to calculate clear-sky solar radiation. |
| 1.2 shortwavc.aml | N-hemisphere – corrected version of shortwave.aml. |
| 1.3 shortwavb.aml | Batch-mode version of shortwavc.aml. |
| 1.4 diffuse.aml | Original code of L. Kumar’s routine to calculate diffuse solar radiation. |
| 1.5 diffuseb.aml | Batch-mode version of diffuse.aml. |
| 1.6 solrad.aml | Extensively updated version of shortwavc.aml to calculate actual direct solar radiation. Two files including transmittance data and lapse rate data need to be present to calculate the solar radiation grids. |
| 1.7 solradb.aml | Batch-mode version of solrad.aml. |
| 1.8 solarflux.aml | Original code of P. Rich’s routine to calculate clear-sky solar radiation. The routine calls a series of subsequent AMLs to perform the task. These sub-routines are not listed here. |
| 2.1 tave.aml | AML that allows to generate monthly average temperature maps using a DEM and a point coverage, which has information on average temperature that is re-scaled to 0 m.a.s.l. based on adiabatic lapse rates. The lapse rates have to be set in the AML. |
| 2.2 mowinreg.aml | AML that allows to downscale monthly PRISM or DAYMET climate maps (1-4.5km grid size) to a finer resolution DEM of choice. The routine calls a Fortran program. This program performs a least-square regression between climate and elevation in a moving window. The output of the regression results (lapse rate and intercept) are stored in an ASCII-Grid format. The logic behind this procedure is that originally, regression techniques were used as well to generate the coarse-scale climate grids. Using regressions in a moving window aims at detecting the "hidden" regression paramters. Once these parameters are detected, they can be spatially interpolated to finer scales - to the scale of the high resolution DEM. Finally, the climate map is generated using the finer scale DEM and the interpolated regression parameters. The latter should now be in the same projection and should have the same dimensions and size as the high-resolution DEM. This usually requires an additional re-projection step prior to interpolating the lattice containing the regression results. |
| 3.1 etp_jen.aml | AML that allows to calculate the potential evapotranspiration based on the empirical equation of Jensen and Haise. This eqn. was specifically optimized for the arid Intermountain West. |
| 3.2 etp_stu.aml | AML that allows to calculate the potential evapotranspiration based on the empirical equation of Caprio, termed the Solar Thermal Unit concept. This eqn. was applied to various climate regimes all over the Northern Hemisphere. |
| 3.3 etp_trc.aml | AML that allows to calculate the potential evapotranspiration based on the empirical equation of Turc. This eqn. was specifically designed for the humid climates of Western Europe (France). |
| 4.1 toposcale.aml | AML that allows to identify topographic features (ridge, slope, toe slope, etc) at various spatial scales, and to hierarchically integrate these features into a single grid. The resulting grid displays the most extreme deviations from a homogenous surface as encountered in any of the various temporary grids (which represent a topo-position analysis based on a specific spatial scale). |
| 4.2 topoclass.aml | AML that allows to classify the resulting integrated grid into a grid containing class values only. |
| 5.1 geoclass.aml | AML that enables a classification of surface geology based on ecological principles. Geological map units (usually defined based on time of genesis) are reclassified to simple units that have similar impact on biotic units (i.e. similar carbonate content, similar clay content, similar coarse fragment fraction, etc.). |
| 5.2 soilprop.aml | AML that enables a classification of soil properties based on topographic position and surface geology (a simplified classification of the geological units). |
| 5.3 bucket.aml | This AML generates a soil bucket grid as used in the site water balance (SWB) model. |
| 6.1 swb.aml | This AML generates a map of the site water balance of each pixel, integrating monthly maps of precipitation and potential evapotranspiration over time. The soil bucket is filled with positive differences of precipitation minus Etp until the bucket is filled. No water in excess of the pixel-wise holding capacity (which is the soil bucket) is allowed to be stored. |
