Dhemeter: Data Hub for Environmental and METEorological Resources

Dhemeter is a weather and environmental data aggregator. It is developed using a microservices architecture to handle a wide variety of data from various providers, such as NOAA, ECMWF, Eumetsat, Météo-France, DWD, and Copernicus. The implementation of aggregation, concatenation, and consistency functionalities has been successfully executed for meteorological data. This versatile tool accommodates numerical model data, in-situ observations, remote sensing data, and reanalyses, allowing for online data retrieval from multiple sources.

Key features of the aggregator include:

• Concatenation of Multiple Data Sources: Users can combine data according to selected categories such as Observations, Forecasts, and Reanalyses.
• Standardization of Physical Data: This involves spatial and temporal interpolation as well as geographical selections to ensure uniformity.
• Storage of Resulting Data Structures: The data is stored in a pivot format that facilitates access and distribution of scientific data, specifically in the NetCDF format.

The microservices architecture of the aggregator allows for the extensibility of the offered data catalog, and an API is available for users to make direct queries to chosen data sources.

In the short to medium term, the goal is to enhance the tool further, evolving it into a comprehensive data distribution and aggregation system that centralizes and simplifies access to various types of data, including meteorological, oceanographic, and air quality data.

Dhemeter focuses on ease of use, extensibility, scalability, and customization, offering users capabilities for data fusion and harmonization.
