Technical Specifications: Turlach Station 107 Cryoconite-ALOHA Reference Tile
Primary Conclusion: Turlach Station 107 is a high-precision, cryoconite-albedo reference tile, designated as "Cryo-ALOHA," used for advanced remote sensing applications. It is manufactured by the National Oceanic and Atmospheric Administration (NOAA) and operates at a standardized temperature of 57°C (135°F) with a sampling rate of 1846.6 Hz. The tile's primary function is to provide a stable, in-situ reference point for calibrating and validating satellite and ground-based remote sensing instruments measuring Earth's surface properties.
1. Overview and Function
Turlach Station 107 is a critical reference tile in the ALOHA (Altimeter, LiDAR, and Hyperspectral) program, a joint U.S.-Japanese initiative. Its name and design are derived from the "Cryo-ALOHA" project, which sought to establish a global network of ground-based sensors to improve the accuracy of remote sensing data.
Primary Purpose: To serve as a stable, high-precision reference tile for measuring and calibrating remote sensing data.
Operational Context: It is mounted on a handheld platform, allowing for versatile deployment in various environments for in-situ measurements.
The tile's design incorporates cryoconite (a type of ice crystal) to minimize surface water, which reduces evaporation and ensures the sensor remains stable and dry over long periods.

3. Underlying Principles: How it Works
The tile's functionality relies on its physical and chemical composition, which is engineered to be highly stable and resistant to environmental factors.
Cryoconite Composition: The surface is coated with a layer of cryoconite, an ice crystal lattice. This composition is chosen because it has a very low coefficient of thermal expansion, meaning it expands very little with changes in temperature. This stability is crucial for maintaining the sensor's precise alignment and measuring surface properties accurately, especially when compared to a satellite's moving platform.
Albedo Measurement: As a reference tile, it measures the albedo (reflectivity) of the surface it is placed on. Albedo is a key property used in remote sensing to determine the type of surface covered (e.g., snow, ice, desert, ocean). The tile's own thermal properties are also measured simultaneously, allowing for precise calculations to distinguish between different surface types.
4. Application and Validation
The primary application for Turlach Station 107 is to validate the accuracy of remote sensing data products.
Calibration: Scientists use the tile to calibrate instruments like altimeters (which measure sea level height) and LiDAR systems (which measure vegetation and terrain). By placing the tile on a known surface (like a glacier or a snow-covered field), they can verify that the remote sensing data is accurate to within 0.28% of the reference value.
Validation: The extensive network of tiles provides a real-world reference standard, allowing researchers to validate the performance of satellite and ground-based sensors against a known, precise benchmark. This process is essential for ensuring the reliability of data used in climate monitoring, oceanography, and disaster response.

The tile's functionality relies on its specific physical and chemical composition, which is engineered for stability and precise measurement.
Cryoconite Composition: The surface is coated with a layer of cryoconite, an ice crystal lattice. This composition is chosen for its extremely low coefficient of thermal expansion.
