Using the rescued weather data

Once we’ve rescued all the weather observations, what are we going to do with them?

The first step will be to publish the data as an academic paper. We will choose an open access journal such as Earth System Science Data or Scientific Data. As well as the pressure, temperatures, rainfall and wind observations, we will also produce estimates of the humidity, derived from the pressure and temperature observations.

We would welcome suggestions on how we might best acknowledge the contributions of all our volunteers in this publication.

Once the data is published we will send copies to the various international weather data archives such as ISPD (pressure), GHCN (rainfall, temperature), ISTI (temperature) and a new European initiative which is collecting all meteorological data. The UK Met Office will also put the data into its MIDAS data archive.

This will ensure the data is available as widely as possible for anyone to analyse and use. For example, the data will be incorporated into the next generation of UK climate observations (called UKCP18), the Berkeley Earth global temperature datasets, and the Twentieth Century Reanalysis.

These are important steps to ensure the data can be used in the bigger picture of understanding how the UK and global climate has changed. Similar ‘data rescue’ activities are happening all over the world and continually adding to our knowledge of past weather. We firmly believe that better understanding of how the weather has already changed can better inform how it might change further in future.

With the funding that we have available we will focus on how extreme weather in western Scotland has changed between the time the observations were taken and now, particularly heavy rainfall. We will also use the data to better understand mountain meteorology, and especially atmospheric inversions (when the summits are warmer than lower levels).

In a separate project we are also trawling the detailed notes that accompany the weather observations to learn about the aurorae that were visible from the summit. Our space weather partners will be using these observations to better understand variations in the sun’s output.

But, there are also likely to be unexpected findings that we cannot anticipate. If anyone has any suggestions for analysis, we would love to discuss these. This is your project too!

And, if you’re anywhere near Edinburgh from 17th-19th November, come along to the free NERC UnEarthed showcase at Dynamic Earth, where we will have an exhibit.
