Abstract

A method, apparatus and computer program product are provided for weather station data usage based on weather data confidence. In the context of a method, the method includes receiving historical weather data associated with a candidate weather station and plurality of weather stations, determining distances between a candidate weather station and respective ones of the plurality of weather stations, and generating a station to station location based model of weather attribute errors associated with the distances between the candidate weather station and the respective weather stations of the plurality of weather stations.

Claims

1. A method comprising:

receiving weather data and station to station location based models associated with a plurality of candidate weather stations, wherein (a) a model of the station to station location based models corresponds to (i) a respective candidate weather station and (ii) a particular weather attribute and (b) the model is generated based on a difference in weather data for the particular weather attribute between weather data corresponding to the respective candidate weather station and at least one other candidate weather station of the plurality of candidate weather stations;

determining, for the respective candidate weather station and the particular weather attribute, an expected attribute error for the particular weather attribute based on the distance from the respective candidate weather station and the station to station location based model associated with the respective candidate weather station;

determining weather data confidence for the weather station data of the respective candidate weather station for the particular weather attribute based on the expected weather attribute error determined based on the station to station location based models;

determining a weather condition for the particular weather attribute based on the weather data which satisfies a predetermined weather data confidence threshold; and

activating or adjusting control system settings based on the determined weather condition.

2. The method of claim 1 wherein the station to station location based models associated with a plurality of candidate weather stations are generated by a method comprising:

receiving historical weather data associated with a candidate weather station and the plurality of weather stations;

determining distances between the candidate weather station and respective ones of the plurality of weather stations; and

generating the station to station location based model of weather attribute errors associated with the distances between the candidate weather station and the respective weather stations of the plurality of weather stations.

3. The method of claim 2 further comprising:

discarding the weather data that satisfies a predetermined distance threshold.

4. The method of claim 2 further comprising:

discarding the weather data that satisfies a predetermined outlier threshold.

5. The method of claim 2 further comprising:

causing transmission of a weather query.

6. The method of claim 1 further comprising:

causing the weather data to be displayed based on the weather data confidence.

7. The method of claim 1 further comprising:

causing transmission of a weather query.

8. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and computer program code configured to, with the processor, cause the apparatus to at least:

receive weather data and station to station location based models associated with a plurality of candidate weather stations, wherein (a) a model of the station to station location based models corresponds to (i) a respective candidate weather station and (ii) a particular weather attribute and (b) the model is generated based on a difference in weather data for the particular weather attribute between weather data corresponding to the respective candidate weather station and at least one other candidate weather station of the plurality of candidate weather stations;

determine, for the respective candidate weather station, an expected attribute error for the particular weather attribute based on the distance from the respective candidate weather station and the station to station location based model for the particular weather attribute associated with the respective candidate weather station;

determine weather data confidence for the weather station data of the respective candidate weather station based on the expected weather attribute error for the particular weather attribute determined based on the station to station location based models;

determine a weather condition for the particular weather attribute based on the weather data which satisfies a predetermined weather data confidence threshold; and

activate or adjust control system settings based on the determined weather condition.

9. The apparatus of claim 8, wherein the computer program code is configured to generate the station to station location based models of weather attribute errors, with the processor, by causing the apparatus to at least:

receive historical weather data associated with a candidate weather station and the plurality of weather stations;

determine distances between the candidate weather station and respective ones of the plurality of weather stations; and

generate the station to station location based model of weather attribute errors associated with the distances between the candidate weather station and the respective weather stations of the plurality of weather stations.

10. The apparatus of claim 9, wherein the at least one memory and the computer program code are further configured to:

discard the weather data that satisfies a predetermined distance threshold.

11. The apparatus of claim 9, wherein the at least one memory and the computer program code are further configured to:

discard the weather data that satisfies a predetermined outlier threshold.

12. The apparatus of claim 9, wherein the at least one memory and the computer program code are further configured to:

cause transmission of a weather query.

13. The apparatus of claim 8, wherein the at least one memory and the computer program code are further configured to:

cause the weather data to be displayed based on the weather data confidence.

14. The apparatus of claim 8, wherein the at least one memory and the computer program code are further configured to:

cause transmission of a weather query.

15. A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code portions stored therein, the computer-executable program code portions comprising program code instructions configured to:

receive weather data and station to station location based models associated with a plurality of candidate weather stations, wherein (a) a model of the station to station location based models corresponds to (i) a respective candidate weather station and (ii) a particular weather attribute and (b) the model is generated based on a difference in weather data for the particular weather attribute between weather data corresponding to the respective candidate weather station and at least one other candidate weather station of the plurality of candidate weather stations;

determine, for the respective candidate weather station, an expected attribute error for the particular weather attribute based on the distance from the respective candidate weather station and the station to station location based model for the particular weather attribute associated with the respective candidate weather station;

determine weather data confidence for the weather station data of the respective candidate weather station based on the expected weather attribute error for the particular weather attribute determined based on the station to station location based models;

determine a weather condition for the particular weather attribute based on the weather data which satisfies a predetermined weather data confidence threshold; and

activate or adjust control system settings based on the determined weather condition.

16. The computer program product of claim 15 wherein the computer-executable program code portions comprise program code instructions configured to:

generate the station to station location based model of weather attribute errors, wherein generating the station to station location based model of weather attribute errors comprises;
