Short Summary

This paper introduces and documents the PIRAGUAatmosanalysis and PIRAGUAhydroanalysis datasets, which provide comprehensive meteorological and water balance components for the Pyrenees region to support water resource assessment and management.

Objective

• To develop and document two new datasets, PIRAGUAatmosanalysis (daily meteorological variables) and PIRAGUAhydroanalysis (monthly water balance components), to facilitate a comprehensive assessment of current water resources across the Pyrenees region.

Study Configuration

• Spatial Scale: Pyrenees region, encompassing Spain, France, and Andorra.
• Temporal Scale:
  • PIRAGUAatmosanalysis: Daily data for the period 1979–2014.
  • PIRAGUAhydroanalysis: Monthly data for the period 1981–2010.

Methodology and Data

• Models used:
  • SAFRAN reanalysis framework (for PIRAGUAatmosanalysis).
  • SASER hydrological model (for PIRAGUAhydroanalysis).
  • SWAT hydrological model (for PIRAGUAhydroanalysis).
• Data sources:
  • Observational data from Spanish and French meteorological agencies (assimilated into SAFRAN for PIRAGUAatmosanalysis).
  • PIRAGUAatmosanalysis dataset served as forcing input for the SASER and SWAT hydrological models to derive PIRAGUAhydroanalysis.

Main Results

• Development and documentation of the PIRAGUAatmosanalysis dataset, a daily, gridded dataset of near-surface meteorological variables for the Pyrenees (1979–2014).
• Development and documentation of the PIRAGUAhydroanalysis dataset, providing monthly water balance components derived from hydrological models for the Pyrenees (1981–2010).
• Provision of example R scripts for data exploration, an interactive visualization and analysis platform, and access through a dedicated geo-server to enhance data utility and accessibility.

Contributions

• Creation of comprehensive, high-resolution, and cross-border datasets for atmospheric and hydrological water balance components specifically tailored for the Pyrenees region.
• Integration of observational data from both Spanish and French meteorological agencies, enhancing the accuracy and regional applicability of the atmospheric dataset.
• Provision of open-access data and tools (R scripts, visualization platform, geo-server) to foster transparency, reproducibility, and informed decision-making in regional water management and planning.

Funding

• Interreg POCTEFA
