Found yourself needing a new Weather API?

Recently, Dark Sky shared the news that they have joined Apple; we wish them all the best in their new partnership.

You may have also heard that they are no longer accepting signups to their API service, which will be discontinued at the end of 2021. As companies begin to look for new weather providers, we thought it would be useful to share some information on our API service!

Forecasts, Observations and Historical Data

We have a suite of APIs available, including:
o Deterministic, ensemble/probabilistic and monthly weather forecasts
o Real-time and historical weather measurement data, such as:
o Weather station observations
o Rainfall radar
o Lightning
o Solar radiation
o Modelled historical weather data

To discuss which options are best for you, feel free to get in touch via info@weatherquest.co.uk.

Developed and Used by Our Meteorologists

Our weather forecast API has been developed in-house by our team our research meteorologists, and was designed with our operational forecasters in mind. The data that goes into our API is used by our meteorologists every single day, to help them provide the highest quality and most accurate forecast possible.

Our forecast methodology is multi-layered, but also relatively simple. We source our forecast data from a variety of well-performing global and high-resolution regional models, including our own Weather Research & Forecasting (WRF) model built and run in-house. This forecast data is used to create a "multi-model blend" dataset.

Post-processing algorithms are then used on a site-by-site basis to increase the accuracy of the forecast based on known (and calculated) model biases from similar past weather events. In the immediate short-term, nowcasting techniques are also adopted to take the current weather situation (such as radar and the latest observations from weather stations) to project forwards over the next few hours. This means that our API feed is being constantly updated to give you the most accurate forecast possible.

Finally, our philosophy since Weatherquest was founded is to always allow our meteorologists to have the final say in any forecast, and so we are passionate in always retaining the ability for forecaster intervention - meaning every forecast you receive will have been examined by a qualified meteorologist, and adjustments made where necessary.

Unique and Interesting Parameters

We offer all the standard variables you would expect to receive in a weather API, including temperature, rainfall, wind and pressure. However, we can also include a range of specialist variables developed by our team.

For the agricultural industry, Spraying Index and Drying Index are considered particularly useful when planning fieldwork, and Growing Degree Hours provides a useful measure of crop development. We also offer Road State and Ground Icing - vital parameters for winter gritting, as well as a variety of variables for offshore energy, including wave information, hub-height wind speeds and gusts and lightning risk.

These are just a handful of the parameters that Weatherquest offer, if you'd like to find out more send an email to info@weatherquest.co.uk.

Smooth Integration

Our datastreams can be incorporated into your external-facing website with ease, integrated into your own operational decision support systems, and can also be used for data analysis on behalf of clients. Whatever you want to use it for, our IT team can make sure your new weather API is up and running as quickly as possible.

The intricacies of high pressure

Even when the weather appears fairly uninteresting during a settled spell, there's usually some things to look at - this plot (below) from midday on 8th January 2018 at Herstmonceux (East Sussex) of temperature with height, measured by instruments attached to a weather balloon, highlights some interesting features.

A temperature inversion is present, a result of dry air sinking through the upper/middle portions of the atmosphere courtesy of an area of high pressure to the east of the British Isles. But this dry, sinking air doesn't reach all the way down to the ground - instead, there is a shallow layer of cold, moist air trapped near the surface. Notice how the temperature at 0.7 miles (3,600 ft) above ground is actually warmer than that near ground level.

The closer the temperature (solid) and dewpoint (dashed) lines are together, the moister the air is. When the air becomes saturated (both lines touching), cloud or fog forms. in this example, a layer of cloud can be determined, its base around 1,000 ft (300 m) above ground. Any hills above 300m would likely experience 'hill fog'.

This layer of stratus cloud can be seen in the satellite image above, its progress northwards blocked somewhat by the higher ground of Wales which sticks out above the inversion.
