Short Summary

This study develops a station-anchored open-data evapotranspiration (ETo) screening workflow for assessing local product compatibility under incomplete meteorological records in the eastern Marmara region.

Objective

• Investigate the feasibility of using open-data reference ETo products as substitutes for station-derived ETo under incomplete meteorological records.

Study Configuration

• Spatial Scale: Eastern Marmara region, Turkey.
• Temporal Scale: 1990–2020.

Methodology and Data

• Models used: Hargreaves-Samani (HS), FAO-56 Penman-Monteith (PM).
• Data sources: TerraClimate v1.1 reference ETo, Turkish State Meteorological Service (MGM) stations.

Main Results

• TerraClimate reproduced the annual ETo cycle strongly but showed station-dependent and calendar-month-dependent biases.
• Train-only monthly-bias and nested L2 residual corrections reduced pooled blocked out-of-sample mean absolute error (MAE).
• Measured-radiation PM subsets at Kocaeli and Yalova showed offsets of −4.42% and +3.37%, respectively.

Contributions

• This study provides a station-anchored open-data ETo screening workflow for assessing local product compatibility under incomplete meteorological records.
• The results highlight the importance of season-aware compatibility screening before using gridded ETo for climate-resilient water-resource planning.

Funding

• [Not specified in the paper]
