Our newest supercomputer has as much computing power as 20,000 normal PCs, and helps us improve the accuracy of our weather forecasts, as well as research climate change.
With over 300,000 books, charts, atlases, journals, articles, microfiche and scientific papers, our library holds one of the most comprehensive collections on meteorology in the world.
We go to great lengths and heights to get the best weather and climate observations - from our purpose-built aircraft to our incredible ship systems.
Our supercomputer is one of the largest in the world - it's capable of carrying out 127 trillion calculations per second.
We have weather records on file dating back to 26 August, 55BC.
The year 2000 was the UK's wettest on record. We measured rainfall of 1,337mm.
