Probe for Windows Help: Forecast Rain and ET
Probe For Windows can use forecast rain and evapotranspiration (ET) when calculating required irrigation, both for the next irrigation and also for the whole season
The total amount of forecast rain in the next 7 days can be calculated for each site,
and the value is left in variable %ForecastRain%.
This could be used in...
- An email with: %ForecastRain% mm rain forecast in the next %dripdays% days
- A graph report (.gpt): %ForecastRain%:amt:1 rain is forecast in the next %dripdays% days
- In a text report (.rpt): Formula: ForecastRain, format: AMT
- On the sites screen (.spt): Formula: ForecastRain
The predicted rainfalls will also be shown on the time graph if GraphMenu/Options/Local tab: Time Graph Plot delivered rain: (using graph style='Rain/Predicted' [ID=80])
Predicted effective rainfalls (over FULL = runoff) will only be plotted if they are different from the forecast amount (graph style='Rain/Predicted/Effective' [ID=79])
Forecast ET can be used to schedule the next irrigation - see with Forecast. The current value of ForecastET will be shown
The value of ET will be shown on the graph if Formual with source=ForecastDWU
A Location is an geographic area that ha steh same forceat. All site sallocatd to a Location will us ethe same forcats
Each location has 'Scenario's - rain, ET, temperrature, etc (scenario is a sill name) Each scenario can get its vale indepdantly from oteh rscenarios in the location Thsi allows ET, fro example, come from a diffrent forcast service thatn 'remperateure It also allow the value sto come from historical wetaherfiels - n
Each Scenario csbv file that is downlaode from a Forcast, and its own options teh calculate
A location needs adding for each area, and a scenario needs to be added for each value
Each is then allocated to a location on ReadingsMenu/Scheduling tabb???
When a location is selected, the same location can be set for all oteh rsites for the groeer
ProbeMenu/Forecast
There are various on-line providers of weather forecasts. Some are free, and some charge for specialised reuirements
Most require the GPS lat/lon of a forecast location
Sentek users can get a forecast that includes both rain and evapotranspiration (ET).
A Meteoblue forecast location and API Key is required, which can be got from an IrrimaxLive account
The location of a site is set ReadingsMenu/Scheduling tab: Options
When a site is allcated to a location, all sites belonging to that grower can be optionally set to the same location.
Each grower can also be allocated to a location - see FarmMenu/Edit tab: General
Users will be asked if they want to set all sites for the grower to the same location
ProbeMenu/Forecast
To enable forecast ???
- Add a location for each forecast area
- For that location, add a Rain and/or ET ???
tab: Locations
- Only active Locations can be selected for a site
tab: Scenarios
- File: examplehigh.ran - a comma-delimited text file with rain amounts
- Date Column: the column in the file that has the date
- Adjust dates: If a 'historical' weather file is being used, the date in the file could be for a previous season
if , the date will be adjusted so that it is within the current season (??) - Rain Column: the column in the data file that has the rain amount
- Total-by-day: Some weather files will have a value every hour
if a daily total rainfall will be calculated - Header lines: the number of header lines if the file that should be skipped - default = 1
- Minimum: rainfalls below this value will be ignored
- Units: the units of the data in the data file - mm or ins. (All internal calculations are in metric)
tab: Values
- Displays the rainfall events and the values found in the file
- This tab is just for checking - the calculated
%rainfall%amount for each site will be from the date of the last reading, for the following 7 days - A period can be specified for calculating total rain in the period
- Rainfalls found in the period will be highlighted
- The total amount in the period will be shown
- - re-load all rainfall files to update values
tab: Download
The rainfall files are read from the shared\ folder (eg: shared\examplehigh.ran)
These files can also be downloaded from a web site
Method:
- http The file must be on a publically available server eg.
Server:http://www.rsne.com.au/ftp/examplehigh.ran - Open Weather: to be implemented
- Irrimax
The forecast file is downloaded from Sentek Irrimax
Server: Name of the Irrimax database
download file for this scenario
Irrimax download requires the start date of the forecast, and a key (supplied by Sentek)
download files for all scenario's
At startup - download all active files at Start-Up
tab: files
Name and location of files that contains the list of Regions and then list of Rainfall Scenarios
Defaults:
shared\regions.txt, shared\rainfall.txt
'3.1.211 ' attempt to append downloaded data to existing file - abandoned ' file re-downloaded if file date is different ' option download from Now-2 days note: saved in INI, not forecast file ' CalculateTotal - ET - use fractional days ' append text to %Forecast% [5 days]
