Please be aware that we are implementing a modification of one of the selection widgets on the download forms of the following SIS datasets:

- [Agrometeorological indicators from 1979 to present derived from reanalysis](https://cds.climate.copernicus.eu/cdsapp#!/dataset/sis-agrometeorological-indicators)
- [Climatic suitability for the presence and seasonal activity of the Aedes albopictus mosquito for Europe derived from climate projections](https://cds.climate.copernicus.eu/cdsapp#!/dataset/sis-health-vector)
- [Heat waves and cold spells in Europe derived from climate projections](https://cds.climate.copernicus.eu/cdsapp#!/dataset/sis-heat-and-cold-spells)
- [Ocean surface wave indicators for the European coast from 1977 to 2100 derived from climate projections](https://cds.climate.copernicus.eu/cdsapp#!/dataset/sis-ocean-wave-indicators)
- [Ship performance along standard shipping routes derived from reanalysis and seasonal forecasts](https://cds.climate.copernicus.eu/cdsapp#!/dataset/sis-shipping-consumption-on-routes)
- [Temperature statistics for Europe derived from climate projections](https://cds.climate.copernicus.eu/cdsapp#!/dataset/sis-temperature-statistics)
- [Mountain tourism meteorological and snow indicators for Europe from 1950 to 2100 derived from reanalysis and climate projections](https://cds.climate.copernicus.eu/cdsapp#!/dataset/sis-tourism-snow-indicators)
- [Water sector indicators of hydrological change across Europe from 2011 to 2095 derived from climate simulations](https://cds.climate.copernicus.eu/cdsapp#!/dataset/sis-water-hydrological-change)

The affected widgets are those including the word "Statistics" (e.g. Statistics or Ensemble Statistics).

As a result of the modification of the widget name, the corresponding API request syntax also changes. To avoid disappointment with failing API data requests, **please check your API scripts and update as necessary** (i.e. update 'statistics' to ' **statistic**' or update 'ensemble statistics' to ' **ensemble statistic**' as applicable).

We strongly recommend that you **check you have the correct syntax for your API script by using the 'Show API request' button on the applicable CDS Download form.**

We apologise for the inconvenience this may cause.

For any enquiries or feedback regarding the above, please [contact us](https://climate.copernicus.eu/help-and-support).
