Weather

The weather in PCSE is generally historical data provided by the NASA Power API. This weather module has data from 1984 to 2023 with most latitudes and longitudes available. For configuring the weather to be used in a crop simulation, see SiteCalendar.

As the simulation processes, the pcse.NASAPowerWeatherProvider module will continue to draw daily weather until the simulation terminates.

Caution

Starting a simulation with the year 2023 and running the simulation for 2 years may result in an error, as the ``pcse.NASAPowerWeatherProvider``can no longer continue to draw weather.

In multi-year perennial simulations, the weather for a given year is generally drawn randomly from years in the range [1984, 2023]. This behavior simulates a different weather for each year, and ensures that the simulation never runs outlined of daily weather to draw from. If this is not desired behavior, it can be overridden in pcse_gym.envs.wofost_base.NPK_Env.
