The proposed framework is limited to downscaling daily temperature and precipitation from ERA5
Research gap analysis derived from 3 earth_science papers in our local library.
The gap
The proposed framework is limited to downscaling daily temperature and precipitation from ERA5. The framework may not be applicable to other reanalysis products or variables. The evaluation procedure is similar to leave-one-out cross-validation, which may not be suitable for all applications.
Evidence profile
Sourced from the stated research gap and abstract and limitations section of the source papers, classified as general, drawn from work published between 2019 and 2026, spanning 3 journals. Those papers have been cited 225 times in total.

The lack of consistency in the representation of key variables across different reanalysis datasets. The limited ability of reanalysis datasets to capture long-term trends and responses to extreme climatic events. The persistent challenges in historical reanalysis, particularly in the pre-satellite era.

However, the new‐era reanalysis products (ERA‐5, Climate Forecast System Reanalysis, ERA‐Interim, Modern Era Retrospective Analysis for Research and Applications version 2, and Japanese 55‐year Reanalysis Project) have not been evaluated for the hydrologic applications in India specially to understand if ERA‐5 outperforms the other reanalysis products or not.
