Sample interview questions: How do you assess the accuracy and reliability of remote sensing-derived land surface temperature measurements?
Sample answer:
Accuracy Assessment:
- Comparison with in-situ measurements: Collect ground-truth data using temperature sensors and compare it with remote sensing-derived LST measurements.
- Intercomparison of different sensors: Compare LST data from multiple satellite sensors or ground-based methods to identify systematic biases and uncertainties.
- Error analysis: Quantify the absolute or relative error of LST measurements by calculating the mean absolute error, root mean square error, or bias.
Reliability Assessment:
- Sensor calibration and validation: Verify the accuracy of satellite sensors through calibration and validation procedures conducted by space agencies or independent research centers.
- Data quality assessment: Examine the quality flags provided with LST products to identify potential errors or uncertainties due to cloud cover, atmospheric conditions, or data artifacts.
- Temporal and spatial consistency: Evaluate … Read full answer
