What are the advantages of CMIP7 climate data compared to CMIP6? When will it be available for research purposes?

I am working on enhancing the SWAT+ model for my PhD research and need to modify its source code. Could anyone suggest:

Any guidance would be greatly appreciated. Thank you!

I am trying to assess the quantitative impact of climate change on hydrological regime of a semi-arid subbain; and I can not select among different customary models.

please help me based on your knowlege and experience in water resources modeling.

SWAT? SWAT+? WEAP? HEC-HMS? IHACRES? or something else?

Hi all,

Does anybody know how or where I can download a multi-model mean time series of the CMIP6 climate projection scenarios a certain location? It seems I can only find output from separate models, which is a lot work to put them together.

Thanks

Hi,

Could anyone guide how to draw Taylor diagrams and which software is usually used for this purpose?

Regards

I want to compare ERA Interim precipitation estimates with ground measurements so i do not know to convert the data from kg/m2/s to mm/day.

Thanks in advance

The influence of elevated atmospheric CO₂ (eCO₂), particularly under future scenarios exceeding 660 ppm, presents a critical uncertainty in modeling the water-food nexus. eCO₂ affects both plant physiology (e.g., stomatal conductance, transpiration, biomass accumulation) and hydrological processes (e.g., evapotranspiration, runoff generation), making its integration into modeling frameworks increasingly important.

I am currently exploring which hydrological and crop growth models are capable of incorporating eCO₂ effects, and to what extent they represent the associated physiological and hydrological mechanisms. Moreover, I am interested in understanding the complexity of these models in terms of how CO₂ response functions are embedded in their algorithms and equations.

Could you recommend hydrologic and crop models that can simulate eCO₂ impacts realistically? How do these models differ in their assumptions, parameterization, and overall representation of CO₂-driven processes?

Your insights, experiences, and any relevant literature would be greatly appreciated.

Wheat cultivation in semi-arid regions faces several challenges including low soil moisture, high temperatures, erratic rainfall and soil degradation. To ensure food security and sustainable production it is crucial to adopt climate smart agricultural practices that can improve yield, soil health and water efficiency.

I am particularly interested in:

I would appreciate insights from researchers, agronomists and farmers who have worked in similar climates. Additionally, any references to recent studies, models or innovative technologies that enhance wheat yield under semi arid conditions would be highly valuable.

Dear scientists! What is the most common method you recommend for determining potential evapotranspiration?
