Each data source 102 provides and can be used for producing the information of irrigating control information, comprises for example ET value.This ET value is calculated based on several parameters, comprises for example relative moisture, soil temperature, air themperature, wind speed and solar radiation.The quantity of parameter is according to the method that is used to calculate the ET value and difference.Data source 102a-c provides the information of relevant these parameters jointly.Each data source 102 can provide the information of corresponding one or more parameters.This information is used to calculate the ET value subsequently, will further specify below.Use is because irrigation system 106 residing zones do not have enough measurement devices or the local information of resource to obtain to determine that this regional ET value needs from the data of non-local data source 102a-c.
The data source 102a-c meaning non-indigenous is that they are not positioned at the general area identical with irrigation system 106.For example, data source provides the National Meteorological Bureau of the overall Weather information of the U.S.; Other data sources comprise from the database of each university and government organs or data to be supplied with.The implication that should understand term " non-this locality " is not to limit by physical distance is strict; " non-this locality " also can refer to experience the zone of different substantially weather conditions.For example, two zones are adjacent to each other physically; But they can non-each other this locality because since different geographical topology and different terrain they have different substantially weather conditions.As previously mentioned, data source 102a-c provides the data of the various parameters of the relevant ET value that is used to calculate the zone that irrigation system 106 covers jointly.For example, the data of collecting from data source 102a-c comprise surface observation, souding upper-air observation, and SST and current overall initialization 4D (4 dimension) grid, or the like.
Data from data source 102a-c are transmitted to processor 104.Should note to send processor 104 to by some modes, comprise for example by computer network, as the internet from the data of data source 102a-c.Open and instruction based on providing at this one skilled in the art will know that other modes and/or the method that data are sent to processor 104 from data source 102a-c according to the present invention.
The required ET value in each specific region that processor 104 is covered with calculating irrigation system 106 by processing said data.At first, the necessary weather parameters in the processor 104 calculating 4D spaces.
Weather parameters in the 4D space is calculated as follows.Gridding landform altitude, vegetation and land use flatly are interpolated on each mesoscale territory.Input field such as soil types, vegetation part and dark soil temperature are filled from historical data.
Subsequently, input is interpolated into each mesoscale territory to the 4D gridding meteorology analysis of stress level and with those analyses from global grid.The step of front is carried out stress level and surface analysis.These levels are carried out two-dimensional interpolation to guarantee the grid of complete filling.
Next, adjust overall initialization on each mesoscale grid by merging from the observation data of data source 102a-c.Use dissimilar observation datas, comprise for example traditional from surface and high-altitude data to temperature, humidity, the direct observation of wind, and remote sense data are as radar and satellite image.The four-dimensional variational technique of three peacekeepings is carried out integration and implementation quality control to data, thereby removes problematic data so that improve overall initialization grid.
Calculate and format the initial boundary condition subsequently to obtain the input of numerical weather model.Understanding is depended on that each application-specific can use some different numerical weather models.Based on the open and instruction that provides at this, one skilled in the art will know that how to select suitable numerical weather model according to the present invention.For example, be converted to " S " coordinate system in following stress level data of bounded condition in the 4D space in (x, y, z and time).The integral mean that initial analysis can comprise is dispersed or noise conditions is removed subsequently to create the stable ground state of numerical weather model.
Use numerical weather model, and suitable physics option, weather parameters necessary in the 4D space calculated subsequently.This is the totally bounded 4D grid on room and time with known beginning and termination condition.
Calculate weather parameters and can disclose available modeling application (not shown) execution by processor 104 usefulness are some.Can revise these modelings uses to carry out above-mentioned functions.It is PSU/NCAR mesoscale model (being known as MM5) that so known modeling is used.MM5 is the sigma coordinate model that confined area, nonfluid are static, follow landform, is designed to emulation or prediction mesoscale atmospheric air circulation.It is WRF (weather research and the forecast) model of being created by UCAR (association of atmospheric research university) that another this modeling is used.Based on the open and instruction that provides at this, one skilled in the art will know that how to select according to the present invention and revise various available modelings and use.
Be used for calculating the ET value of target location, 2D space subsequently from the weather parameters of the calculating of numerical weather model output.The required corresponding weather parameters of ET value of calculating this target location is extracted from specific x, y, z and time location.
The ET value of calculating subsequently in the target location is also created the 2D gridding surface of 24 hour period.Should understand the ET value can calculate based on one of some different formulas.Open and instruction based on providing at this one skilled in the art will know that according to the present invention how to select suitable formula according to each particular case.
At last, eliminate any illusion, the edge effect and unusual that produces by mesoscale net boundary condition and/or error.
In addition, in one embodiment, processor 104 was at first encrypted before transmission calculating ET value is to irrigation system 106 or change it on mathematics.Irrigation system 106 is equipped with corresponding decipherment algorithm to calculate the ET value with deciphering or recovery.
But in an alternative embodiment, processor 104 obtains after the weather parameters, and these weather parameters are delivered to irrigation system 106.Use the weather parameters of transmitting, irrigation system 106 is calculated suitable ET value subsequently.Alternatively, processor 104 can be encrypted weather parameters and irrigation system 106 and is equipped with corresponding decipherment algorithm with deciphering or recover these data before weather parameters is passed to irrigation system 106.
