Getting Started

What You Need to Get Started

To begin your journey with MJOcast, make sure you have the following:

  1. Hindcast Files: Organize your hindcast files into different initializations, and name them with the initialization time (e.g., CESM2_init_May032002.nc).

    1.1. Forecast Files: These should encompass all ensembles and can be arranged in various grid orientations (such as lat, lon, ensemble, time or time, ensemble, lat, lon, etc.).

    1.2. Required Variables: Forecast files must include zonal wind at 200mb, zonal wind at 850mb, and Outgoing Longwave Radiation.

    1.3. Geographical Orientation: Files can be either in the -180°E to 180°W range or 0° to 360°W, and oriented from 90°S to 90°N or 90°N to 90°S.

  2. Positive Attitude: A can-do attitude will make your forecasting experience even more rewarding!

Optional

  1. User-Provided Observations: If you have your own observations, you can integrate them.

    3.1. Observation Generation: Consult the provided preprocessing folder in the code repository to generate observations from your own .nc files.

    3.2. Default Option: Alternatively, utilize the provided ERA5 observations (spanning 1950-2022) from the GitHub repository.

  2. User-Provided Lead-Time Dependent Climatology: If available, incorporate your own climatology.

    4.1. Climatology Generation: Explore the preprocessing folder in the code repository to create this lead-time dependent climatology.

    4.2. Value of Climatology: Discover the benefits of using this climatology as explained below. See Why Provide a Lead-Time Dependent Model Climatology in S2S Forecasting? for the details.

    4.3. Default Option: Alternatively, the ERA5 data (or provided observations) will be used.

Prepare these essentials to embark on your journey with MJOforecaster and unlock its full potential.
