# Overview

Based on records from weather stations, satellite data, and climate projections,
**Meteonorm Climate** provides time series that represent past, current, and future
weather conditions for any location on Earth.

We provide two types of time series:

- **Typical Meteorological Years (TMY)**: A TMY represents a statistically typical year
  with respect to some reference period – past or future. A TMY is generated
  stochastically. It is not representative of a _specific_ historical year. Instead,
  it describes a year that is typical for the long-term climate of a given location and
  reference period.
- **Actual Meteorological Years (AMY)**: AMYs are historical time series that represent
  the _actual_ weather conditions at specific points in time. AMYs are based on satellite
  observations and reanalysis datasets, post-processed for any location
  on Earth. AMYs are available from 2010 to the current year.
