Vichayito Thermal Refuge: Sand Temperature Data and Climate Projections

From 2017 to 2023, meteorological records from the El Alto station provide local reference data. The dataset includes raw sand temperature measurements from September to December 2024 at a depth of 58 cm, alongside processed CMIP6 climate projections downscaled to the Vichayito, Peru nesting site. Daphne Lisbeth Arenas Yance authored this collection to study temperature trends and sex ratio implications for Lepidochelys olivacea.

Use Cases

• Validate gridded climate data products based on local station records.
• Project future sand temperatures through 2100 based on downscaled CMIP6 model ensembles.
• Analyze the relationship between air and sand temperature using an established linear regression.
• Evaluate biological thresholds for sea turtle sex determination based on projected temperatures.

Strengths

• Includes daily meteorological records spanning 7 years (2017-2023).
• Contains raw in situ sand temperature data recorded every 30 minutes.
• Provides processed CMIP6 projections downscaled to a specific nesting site.
• Files are structured for a clear analytical workflow (raw, processed, projections).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to a single coastal site in Peru.
