NAME

LocationforecastLTS - Weather forecast for a specified place, long term support.

DESCRIPTION

This product delivers similar data as locationforecast, but for this product we will support a deprecated version for at least 3 months. Locationforecast will probably be updated more frequently and might have shorter life span for deprecated versions.

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

Please note that available parameters will wary depending on location and forecast time.

Locations inside Norway will have probability elements for temperature, wind, symbol and precipitation. The precipitation element have additional attributes for max and minimum values.

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%>

The list of numbers and ids for the current symbol elements can be found at $webroot/weathericon/1.1/documentation.

Bugs

• msl parameter: the msl parameter are used to adjust the temperature according to adiabatic changes. For locations inside Norway we use our own corrections schemes for the first 48 hours and the parameter will have no effect. It will however affect the temperature for the last 7 days of the forecast. The altitude reported in the XML is the same as the parameter.

USAGE

Parameters

• lat (latitude), in decimal degrees, mandatory
• lon (longtitude), in decimal degrees, mandatory
• msl (whole meters above sea level (integers)), optional
