|August 8, 2026
Summary
The PIRAGUA project offers new atmospheric and hydrological datasets for the Pyrenees, aiding water resource assessment. These datasets support improved regional water management and planning.
Area of Science:
- Environmental Science
- Hydrology
- Climatology
Background:
- Comprehensive water resource assessment is crucial for the Pyrenees region (Spain, France, Andorra).
- Existing data limitations hinder detailed hydrological and land-surface modeling.
Purpose of the Study:
- To introduce the PIRAGUA_atmos_analysis and PIRAGUA_hydro_analysis datasets.
- To support water resource assessment and inform regional water management.
Main Methods:
- Development of PIRAGUA_atmos_analysis: daily, gridded near-surface meteorological variables (1979-2014) using SAFRAN reanalysis and observational data.
- Development of PIRAGUA_hydro_analysis: monthly water balance components (1981-2010) from SASER and SWAT models, driven by PIRAGUA_atmos_analysis.
- Provision of R scripts, interactive platform, and geo-server for data access and analysis.
Main Results:
- Creation of daily meteorological and monthly water balance datasets for the Pyrenees.
- Demonstration of dataset utility through example analyses and visualizations.
- Establishment of accessible data resources for researchers and water managers.
Conclusions:
- The PIRAGUA datasets provide valuable, integrated information for Pyrenean water resource studies.
- Enhanced data accessibility and analysis tools promote transparency and reproducibility.
- These resources facilitate informed decision-making in regional water management and planning.

01:21Isochoric and Isobaric Processes
A thermodynamic process that occurs at constant volume is called an isochoric process. According to the first law of thermodynamics, heat supplied or removed from the system is partially utilized to perform work and change the internal energy of the system. However, in an isochoric process, the volume remains constant. Hence, the work done by the system is zero. Therefore, the exchange of heat changes the internal energy of the system only.

01:12Precipitation Processes
The experimental conditions in a gravimetric analysis should be optimized to maximize the particle size and purity of the obtained precipitate. Ideally, the concentration of the precipitating reagent should be low with effective stirring to maintain low relative supersaturation for the growth of large crystals. In homogeneous precipitation, the precipitant is slowly generated by a chemical reaction in the solution to avoid local reagent excesses. For example, urea decomposes gradually to...
01:00The Water Cycle
The Earth’s hydrosphere includes all of the areas where the storage and movement of water occurs. Since water is the basis of all living processes, the cycling of water is extremely important to ecosystem dynamics.
01:21Precipitation Titration Curve: Analysis
The precipitation titration curve demonstrates the change in concentration of one reactant with the volume of titrant added. During the titration of chloride ions with silver nitrate, the precipitation titration curve is divided into three regions: before, at, and after the equivalence point. Before the equivalence point, low redissolution of the sparingly soluble silver chloride precipitate gives a low silver ion concentration. However, in the second region, representing the equivalence point,...
01:23States of Water
Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...
