COSMOS-UK website help

The Network

The map on The Network page shows the locations of each COSMOS-UK site. Clicking on a site on the map or the list will take you to the site’s details page.

The Filter sites text box allows you to quickly find a site of choice by typing a few letters.


The Data page has near real-time COSMOS-UK data available.


The map tab shows a map of all the COSMOS-UK sites coloured up by the value in the dataset key for the chosen date (the default date is yesterday). 

You can change dataset between Volumetric water content and Soil wetness status. 

The map will update as you step through the days either with the calendar or the forward and backward arrows.

Clicking a site on the map shows you the value of the selected dataset for that site on the chosen date. You can click on the site name to go to the site’s details page.

Time-series data

The time-series tab shows time-series graphs for all sites within the COSMOS-UK network.

You can choose a time period, or a date range which will update all the graphs. 

On the time period tab, changing the end date will show the selected time period up until that date. For example, an end date of 2022-05-10 and a time period of 3 months will show data from 10 February 2022 to 10 May 2022.

You can change the parameter to any of the parameters that are measured by the sensors.

You can filter to a subset of sites, such as East Midlands by changing the Sites select box.

Clicking on a site name will take you to the site’s detail page.



Site information is shown in the table. The (info) buttons explain the data further where needed.

The photos selection below the map is updated occasionally and includes a phenocam image. Click through the images using the arrows. Clicking on an image enlarges it.


The maps show the location of the COSMOS-UK site.

Dynamic land cover map (LCM) map layers and OS map layers are available under the layers button (top right of map). Three recent LCM layers have been chosen so you can compare the change over the years. Please be aware that the LCM layers may take a few moments to load. A question mark button will appear at the top left of the map when an LCM layer is added. The question mark button contains the legend for each LCM layer and an opacity slider. The slider enables the transparency to be altered so multiple layers can be stacked and compared.

In addition to the Mapbox background maps (light, street and satellite layers), OS vector and raster maps are also available which tend to show more detail but are not available until you have zoomed in due to interoperability.

The second map on the page is the Ordnance Survey ‘Leisure map’. Due to differences in projection, this map cannot easily be added to the first map and is only available up until a certain zoom level.

The two zoom buttons allow you to zoom to the site or zoom out to the UK.

Time-series data

This tab is similar to the time-series data tab of the Data page but only shows the time-series graphs specific to that site. The time period and date range functionality works in the same way as the Data page.

The different tabs (summary, weather, soil moisture, soil temperature) group the corresponding graphs.
