NAME

Locationforecast - Weather forecast for a specified place

DESCRIPTION

This modules implements a full forecast for one location, that is, a forecast with several parameters for a nine-day period.

The parameters are temperature, wind speed, wind direction, pressure, precipitation, cloudiness, fog, lowClouds, mediumClouds, highClouds and humidity.

Version 1.8:

This version will also have probability-elements for temperature, wind and symbol (norwegian locations only). A probability element specifies certainty of prognoses for a given parameter for a given time. This certainty is defined by a probabilitycode in the following manner:

    probabilitycode certainty values
    --------------- ----------------
           0        [90% , 100%]
           1        [50% ,  90%>
           2        [ 0% ,  50%>

Note: Longterm forecast/EC-data for norwegian locations will have fewer parameters available than version 1.5.

Historical forecasts

While we only serve current forecasts via the API, you can find historical forecast model data in NetCDF format on http://thredds.met.no/thredds/metno.html.

CHANGELOG

New model backend in beta: 2019-09-09

We're testing a new model (FORTI) which will replace the previous models (AROME, PROFF, EC) shortly. The XML output should identical in structure and validates against the existing schema, but may have some different time intervals. The new model can be tested on the /test endpoint.

The main differences are:

version 1.9 : 2014-05-20

phase out of version 1.5 : 2011-08-16

Version 1.5 of locationforecast will expire at 2011-10-01. Note that log entry below stating that version 1.5 will be available until version 1.9 is released is no longer correct.

version 1.8 : 2010-06-10

New attributes for the precipitation element: minvalue, maxvalue and probability. Note that these attributes will only be available for locations in a limited area in Europe.

1.8 is meant as a transitional version, you may use 1.5 until we release version 1.9. Version 1.7 will be available until 2010-10-01.

version 1.7 : 2010-03-03

Precipitation and symbol values for the first time intervals have been missing in all earlier versions. This has now been corrected.

1.7 is meant as a transitional version, you may use 1.5 until we release version 1.8.

Version 1.6 will be available until 2010-09-01.

version 1.6 : 2009-01-15

1.6 is meant as a transitional version, meaning that you may use 1.5 until we release version 1.8.

version 1.5 : 2008-05-30

1.4 : 2007-12-03

1.3 : 2007-09-12

1.2 : 2007-06-15

1.1 : 2007-04-25

1.0 : 2007-05-15
