17 flights during the ACLOUD campaign in May/June 2017 collected spectral solar irradiance measurements. The data provides solar spectra from 400 to 2155 nm along flight tracks in the Svalbard area at 2 Hz resolution. The measurements were made using the SMART-Albedometer system aboard the Polar 5 aircraft.
Use Cases
- Modeling radiative energy budgets in the Arctic based on spectral irradiance measurements.
- Analyzing solar spectrum variability over polar regions based on airborne flight track data.
- Validating satellite-derived atmospheric measurements based on high-resolution airborne observations.
- Studying cloud and surface albedo effects based on simultaneous up- and downward irradiance data.
Strengths
- 17 flights provide multiple observational samples.
- Spectral range from 400 to 2155 nm captures a wide portion of solar radiation.
- 2 Hz resolution offers high temporal detail along flight paths.
- Simultaneous up- and downward irradiance measurements enable albedo calculations.
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 and temporal bias inherent to the specific campaign.
