The Agrometeorology screen is divided into 5 different maps, as described below:
6.6.1 – Evapotranspiration
6.6.2 – Evapotranspiration ET0
6.6.3 – Potential Evapotranspiration
6.6.4 – Soil Temperature
6.6.5 – Soil Moisture 10 cm
Below, we will discuss each of the maps in detail.
6.6.1 – Evapotranspiration
These maps show evapotranspiration with colors as specified in the map legend. Evapotranspiration is the sum of evaporation (soils, lakes, seas) and transpiration (plants). It assumes a non-irrigated surface, therefore, only naturally available water. Evapotranspiration is expressed in millimeters (mm). This value is an aggregation of conditions over larger areas and may not represent specific conditions in a location, forest, or field. It can be used to make regional comparisons and see gradients.
The Evapotranspiration map (Nº1) illustrates the different amounts of evapotranspiration, using different colors on the map (Nº2). Figure 6.6.1A below illustrates how the Evapotranspiration map is presented on the platform.
Figure 6.6.1A – Evapotranspiration Map
Hovering the mouse over the map will display the different predicted Evapotranspiration values (Nº3) for the selected date. If the user prefers, the map values can be compared to the legend (Nº4) located in the bottom left corner of the screen. The time selector bar (Nº5) will show the different dates available to check evapotranspiration forecasts for the given region. If the user needs to adjust the zoom of the image on the screen, they can use the pre-set Zoom options bar (Nº6) located in the upper right corner of the screen.
6.6.2 – Evapotranspiration ET0 (Reference Evapotranspiration)
This map shows reference evapotranspiration (ET0) in millimeters (mm) according to FAO (Food and Agriculture Organization of the United Nations) standards. The values are calculated based on meteorological variables (radiation, temperature, humidity, wind speed) for a well-irrigated surface completely covered by the crop. The term evapotranspiration describes the loss of water from a vegetated surface through the combined processes of plant transpiration and surface evaporation. This value is an aggregation of conditions over larger areas and may not represent specific conditions in a location, forest, or field. It can be used to make regional comparisons and see gradients.
The Reference Evapotranspiration – ET0 map (Nº1) illustrates the different amounts of reference evapotranspiration, using different colors on the map (Nº2). Figure 6.6.2A below illustrates how the ET0 Evapotranspiration map is presented on the platform.
Figure 6.6.2A – ET0 Evapotranspiration Map
Hovering the mouse over the map will display the different predicted Reference Evapotranspiration values (Nº3) for the selected date. If the user prefers, the map values can be compared to the legend (Nº4) located in the bottom left corner of the screen. The time selector bar (Nº 5) will show the different dates available to check reference evapotranspiration forecasts for the given region. If the user needs to adjust the zoom of the image on the screen, they can use the pre-set Zoom options bar (Nº6) located in the upper right corner of the screen.
6.6.3 – Potential Evapotranspiration (ETp)
These maps show potential evapotranspiration with colors as specified in the map legend. Potential evapotranspiration is a theoretical value and explains the amount of water that would evaporate from a water surface. It is expressed in millimeters (mm). This value is an aggregation of conditions over larger areas and may not represent specific conditions in a location, forest, or field. It can be used to make regional comparisons and see gradients.
The Potential Evapotranspiration – ETp map (Nº1) illustrates the different amounts of potential evapotranspiration, using different colors on the map (Nº2). Figure 6.6.3A below illustrates how the ETp Evapotranspiration map is presented on the platform.
Figure 6.6.3A – Potential Evapotranspiration Map
Hovering the mouse over the map will display the different predicted Potential Evapotranspiration values (Nº3) for the selected date. If the user prefers, the map values can be compared to the legend (Nº4) located in the bottom left corner of the screen. The time selector bar (Nº 5) will show the different dates available to check potential evapotranspiration forecasts for the given region. If the user needs to adjust the zoom of the image on the screen, they can use the pre-set Zoom options bar (Nº6) located in the upper right corner of the screen.
6.6.4 – Soil Temperature (0-10 cm)
The soil temperature maps show the average temperature of the topsoil layer in the area for a specific depth range (e.g., 0-10 cm), visualized with colors, as shown in the color bar. This value is an aggregation of soil conditions over larger areas and may not represent specific conditions at a location, forest, or field. It can be used to make regional comparisons and see gradients.
The Soil Temperature map (Nº 1) illustrates the different temperatures from 0 – 10 cm soil depth, using different colors on the map (Nº2). Figure 6.6.4A below illustrates how the Soil Temperature map is presented on the platform.
Figure 6.6.4A – Soil Temperature Map
Hovering the mouse over the map will display the different predicted Soil Temperature values from 0-10 cm (Nº3) for the selected date. If the user prefers, the map values can be compared to the legend (Nº4) located in the bottom left corner of the screen. The time selector bar (Nº 5) will show the different dates and times available to check soil temperature forecasts for the given region. If the user needs to adjust the zoom of the image on the screen, they can use the pre-set Zoom options bar (Nº6) located in the upper right corner of the screen.
6.6.5 – Soil Moisture (10 cm)
The soil moisture maps show the average moisture of the topsoil layer in the area for a specific depth range (e.g., 0-10 cm), indicated in % and visualized with colors, as shown in the color bar. This value is an aggregation of soil conditions over larger areas and may not represent specific conditions at a location, forest, or field. It can be used to make regional comparisons and see gradients.
The Soil Moisture map (Nº1) illustrates the different percentages of soil moisture using different colors on the map (Nº2). Figure 6.6.5A below illustrates how the Soil Moisture map is presented on the platform.
Figure 6.6.5A – Soil Moisture Map 10 cm
Hovering the mouse over the map will display the different predicted Soil Moisture values at 10 cm (Nº3) for the selected date. If the user prefers, the map values can be compared to the legend (Nº4) located in the bottom left corner of the screen. The time selector bar (Nº5) will show the different dates and times available to check soil moisture forecasts for the given region. If the user needs to adjust the zoom of the image on the screen, they can use the pre-set Zoom options bar (Nº6) located in the upper right corner of the screen.
