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.
