Access to World-Wide HYPE

The HYPE model set-up to the land surface across the globe is called “World-Wide HYPE”. SMHI can choose to share this model (i.e. both source code and the input files) for appointed geographical domains under an Open license (CC BY 4.0) and some appointed user conditions. You can ask for permission to use part of the World-Wide HYPE and depending on your intended purpose, we can reach an agreement. When you download the files, you automatically agree to follow the User Conditions stated below.

The World-Wide HYPE

This HYPE model covers an area of 135 million km2, divided into some 131 300 catchments following the river networks. The average size of catchments is 1020 km2. Catchments of deserts and flood plains have larger areas (~4500 km2, and ~3500 km2, respectively), while catchments in step areas at high altitudes have in general smaller areas. The model uses a large number of Open databases and is calibrated against time-series of various sources of observations (both from in situ monitoring and Earth observations). The World-Wide HYPE model is continuously improved and updated in new model versions at SMHI.

How to obtain a piece of the World?

The World-Wide HYPE (i.e. both source code and the input-data files) for extracted geographical domains can be obtained by sending the form below. We may charge an extraction fee of € 4500 for delivery. As a user of the World-Wide HYPE model you commit to give feedback to SMHI about model evaluations, improvements or modifications of the model input-data files or the HYPE code.

User conditions for the World-Wide HYPE model

1      Background

The hydrological catchment model HYPE (Hydrological Predictions for the Environment) simulates water flow and substances on their way from precipitation through soil, river and lakes to the river outlet. The HYPE code is developed in an open source community (hypecode.smhi.se).

HYPE has been applied in many different regions, e.g. Sweden, Europe, Niger and India. Recently, SMHI has also developed a HYPE-model for the whole world, called World Wide-HYPE.

Party A would like to explore, use and improve the HYPE model for local/regional purposes and party B would like to learn more about hydrology in different regions globally in order to improve the World Wide-HYPE. The Parties therefore enter into this Agreement, in order to specify rights and responsibilities.

4      Feedback

As a user of the World-Wide HYPE Model you commit to give feed-back to the Licensor about model evaluations, improvements or modifications of the Model (or the HYPE code).

Re-purposed data

The World-Wide HYPE uses a number of input data files describing e.g. physiographic characteristics to account for spatial variability in hydrological processes within and between catchments. The model performance can be seen in Table 1. When setting up the World-Wide HYPE, data from original sources (table 2) is transformed to fit this new purpose of use (re-purposed) and then compiled into the formats requested by HYPE input-data files.
