The **Met Mast** is a core asset type in the Bazefield platform representing a single permanent met tower at a power plant. It serves as the foundational asset for collecting, organizing, analyzing, and visualizing detailed meteorological data. Each met mast asset is uniquely identified and associated with a parent site (e.g a “wind farm”), and may serve as the reference PMM for one or many turbines on the farm.

### Functional Description

A **Met Mast** is a collection of measurement equipment mounted on a common tower. Met Masts measure the ambient conditions, including wind speed and direction. The met mast provides information about the **resource layer** for wind power plants, which governs turbine power production (see [Domain Categories](/product/docs/domain-categories) for a broader description of the resource layer and related assets across different power plants). There may be several met towers at a site, as well as sensors at varying heights on a single met tower, to measure different weather conditions across a farm.

## Core Data Model

While the data model of individual met towers may vary by vendor, Bazefield offers a pre-installed *CORE* data model to account for the most common points, events, and attributes relevant to all makes and models of met masts. Model by model variations are then handled typically through smart [Model Inheritance](/product/docs/asset-model). All vendor specific points, calculation, and events are packaged in separate asset model templates, and are not described here.

### Core Attributes

Attributes are fixed key, value pairs used to represent non-time series data associated with each asset (read more about [Attributes](/product/docs/attributes)). While attribute values can differ from asset to asset, critical shared (e.g. *CORE*) attributes defining a met tower asset type, pre-installed in Bazefield are described below. These are often pre-requisite data required for the Bazefield applications to function fully.

Required for basic Bazefield Core functionality

Optional attributes for common additional modelling

*Depending on your version of Bazefield, there may be additional advanced attributes not listed here to support data integrations or migrations with other systems.*
