# Project metadata

**In this document**

We will show you the data sources we use when simulating your Prospect project data.

## Prerequisites

- An active Solargis Prospect account.
- Admin rights, for editing purposes.
- A project created in Prospect with a PV system configured.

## Introduction to solar resource Metadata

The **Metadata page** provides you with detailed insights into the solar resource data we use in Prospect. This metadata is derived from a high-resolution solar and meteorological database developed and operated by Solargis. The database utilizes inputs from various sources, including **NASA**, **ECMWF**(European Centre for Medium-Range Weather Forecasts), and **Solargis's own models and algorithms**.

On this page, you will find comprehensive information about the characteristics of the data used in solar resource assessments. You can explore the sources of data inputs, time representations, Solargis methods used for data processing, and the last modification dates for each parameter. The parameters covered include solar irradiance components like **Global Horizontal Irradiance** (GHI) and **Direct Normal Irradiance** (DNI), as well as meteorological factors such as temperature and precipitation.

By reviewing this metadata, you will gain a deeper understanding of the data's origins, processing methods, and temporal coverage.

> [!TIP]
> **Note**: Metadata will update after every project data update.

#### Key features

- **Data sources**: You will learn about the organizations and datasets used as inputs for the Solargis models.
- **Data processing Methods**: You will understand how data is processed and analyzed to provide solar resource statistics.
- **Temporal coverage**: You will see details on the time periods covered by the data, including both historical and recent updates.
- **Parameter descriptions**: You will have access to a comprehensive list of parameters included in the database, along with their specific characteristics and applications.
