Weather Station Metadata. For weather stations and in-situ measurements, different information will be used in the metadata so that the instruments that measure the variables are described. As well as the entries from the Spatial metadata (excluding spatial-specific entries 5 and 7), these are: Sensor information • Sensor type • Manufacturer • Sensor model • Serial number • Firmware version • Measured variable identifier(s) • Measurement unit of each variable • Accuracy of each variable • Raw sampling rate • Transmission rate Installation information • Connection type / Transmission technology • Position (X, Y information in WGS84) • Height of the instrument above ground (m) • Estimated height of surrounding buildings (m) • Vertical and horizontal orientation of instrument (degrees) • Instrument mounting description • Data format • Photograph(s) of the station and immediate surroundings after installation The above information will be stored in a designed form in Excel, named with the station’s name and the instrument serial number. A consistent set of variable names and measurement units for the weather stations should be agreed upon by the URBANFLUXES Partners before the metadata are populated. It is noted that equipment may need replacing at a particular station and it will be clear when this happens in the framework of the project. To access to the data description with simple tools, contextual information about the data (one per product) will be added in a text based document. This will contain less information than the XML suggested by the INSPIRE Directive or the form containing the weather station metadata. However, this information will be enough to describe the data. Information on the creation date, data source, scale, creator, life span in cases of temporal update will be included in the text file. Information on the source of dataset, time window, expiration date scale of the dataset, owner should be included in both the XML and the TXT files. The final products will be made available through the URBANFLUXES Data Repository hosted in the project’s web server. These products will be accompanied by their metadata, based on the INSPIRE Directive. The non-spatial data will have their own metadata. For multimedia files (photography and video - documentary), keywords based on IPTC protocol for metadata will be used. The list of keywords will be defined by the Consortium. For the documents, keywords from a predefined list can be used either within the text or at the attribu...

A consistent set of variable names and measurement units for the weather stations have been agreed upon by the URBANFLUXES Partners before the metadata are populated. It is noted that equipment may need replacing at a particular station and it will be clear when this happens in the framework of the project.
