A National Climate Monitoring Product is something like the “mean temperature anomaly for the UK” or “Highest daily rainfall total in Spain in 2019”. It’s a summary of the weather and climate for a particular country.
The WMO Expert Team on National Climate Monitoring Products has written guidance to define a set of six basic National Climate Monitoring Products (let’s call them NCMPs from now on) which are:
- Mean temperature anomaly averaged across the country
- Total rainfall anomaly averaged across the country
- Standardised precipitation index averaged across the country
- Warm days averaged across the country
- Cold nights averaged across the country
- Counts of station records (the odd one out)
The idea is that all Met Services that measure temperature and rainfall – which, by survey, we know is most of them – can calculate these products and use them to understand how weather and climate are changing in their country. Some countries produce some or all of these already and the idea’s not to replace what’s already being done, but to give countries with fewer resources a core set of products to aim for.
