Observations represent our main supply of details about how our local weather is altering. They supply direct and unequivocal proof of the impacts of local weather change, are indispensable for the event of seasonal local weather predictions, and are important for validating and bettering the fashions used to simulate future climates below totally different emission eventualities.
The Met Workplace operates a lot of its personal observing networks, while additionally collaborating in international partnerships such because the World Local weather Observing System (GCOS) to facilitate the sharing of worldwide local weather observations. Varied local weather variables are collected from totally different observing programs, high quality checked, and introduced collectively to acquire the absolute best description of the local weather. Alongside long-term local weather monitoring – which you’ll be able to see visualisations of in our local weather dashboard – we additionally want high-quality observations to assist the attribution and prediction of local weather change-induced excessive climate occasions.

The city surroundings
Globally, city areas represent one of the important challenges in present observational functionality. The significance of this problem can’t be understated – internationally an ever-increasing variety of individuals reside and work in city areas and will probably be notably susceptible to the impacts of local weather change and warmth stress. Within the UK, heat-related mortality is projected to extend below a medium emissions situation by round 257% by the 2050s, with this determine even larger in London1.
Met Workplace Basis Scientist, Matthew Fry explains, “On the coronary heart of this lies the truth that metropolis environments aren’t sometimes appropriate with the necessities we comply with when siting our statement networks. Obstructions from buildings are rife, and there’s tarmac in every single place! Regardless of these challenges, we’d like observations to assist us perceive the complexities of the city surroundings; develop and enhance our urban-scale modelling functionality, and to watch modifications over time.”
The expansion of crowdsourced observations
In recent times, the appearance of the ‘good dwelling’ has introduced the potential for climate observations into the houses and gardens of a larger variety of people. Alongside this, a plethora of internet-connected units now have the potential to make and share meteorological observations, at spatial densities that might be merely inconceivable through typical means.
Creating novel crowdsourcing strategies is a extremely lively space of analysis. Some outstanding examples embody deriving air temperature measurements from smartphone battery temperatures, and even detecting UK flood occasions utilizing Twitter! Alongside these oblique crowdsourcing strategies, there exists all kinds of devoted observational networks comprised of citizen-owned and operated units. Corporations akin to Netatmo, Davis, and Oregon Scientific supply dwelling climate stations and related apps/web sites that permit customers to file their very own observations and look at these of others on on-line climate maps.
In 2011, the Met Workplace launched its personal platform – the Climate Observations Web site (WOW) – designed to allow the sharing of present climate observations from throughout the globe, no matter their degree of element or frequency. Observations may come from specifically designed digital, scientific, or wi-fi climate stations, or alternatively from merely searching of the window and recording the current climate state of affairs. In 2020, WOW handed the outstanding milestone of 1.5 billion complete observations and routinely receives over 25 million observations a month.
In addition to being an awesome software for public engagement, knowledge from WOW have been utilized in operational purposes. Following the event of high quality management and bias-correction strategies, knowledge from WOW have been utilized in nowcasting purposes, demonstrating specific use throughout extreme rainfall occasions. Archived WOW observations have additionally confirmed helpful within the detection of drought episodes within the Netherlands and concrete local weather analysis in Berlin.
How can I get entangled?
Local weather change is already affecting each inhabited area of the globe, with human affect contributing to an elevated frequency and depth of utmost climate occasions. Each statement is essential in monitoring and attributing these modifications, with specific worth offered by observations from knowledge sparse areas.
The Met Workplace WOW platform is a free useful resource, with observations submitted there having real purposes in each climate and local weather science. When you’ve got your personal climate station you possibly can register and add knowledge mechanically to WOW, or alternatively you get entangled by recording your personal pictures, observations, or climate impacts through the web site.
