Meteum

How Yandex makes accurate forecasts for specific locations

Signals from space

Several dozen weather satellites are orbiting the Earth
Every minute they take photos of the atmosphere over different parts of the planet
Satellite photos are sent to meteorologists on Earth several times a day

Weather on Earth

Thousands of weather stations observe weather patterns across the planet
They record temperature, humidity, air pressure, precipitation, and wind speed
Based on these observations, meteorologists make forecasts and then check them

Traditional forecasts

a)
Weather agencies make forecasts based on data received from different satellites and weather stations
b)
Each agency has its own formula, so agency forecasts for the same location may vary
c)
Yandex collects forecasts from partners and also makes its own traditional forecast

New technology

Meteum compares traditional forecasts with data from weather stations. It registers repeated errors with the help of MatrixNet machine learning and identifies statistical regularities among them. As a result, a set of rules is developed enabling more accurate forecasts.
One more element is needed to start the forecasting process – your coordinates.

Local features

For an accurate forecast, it is important to know the height of buildings, surface conditions, presence of water bodies nearby, and so on. For example, the weather in the backyard may differ from that on a river bank.

Accurate forecasts everywhere you need them

You can tell Yandex.Weather your location or a place of your choosing. Meteum will create a custom forecast for these coordinates in real time, taking into account the latest weather data.
