Upwelling and downwelling irradiance data were collected from surface drifter buoys off the California and Oregon coast from 04 June 2000 to 24 March 2001. Oregon State University gathered these measurements in support of the Global Ocean Ecosystem Dynamics program. The dataset includes location, sea surface temperature, and optical readings at specific wavebands.
Use Cases
- Modeling phytoplankton dynamics by correlating sea surface temperature with upwelling radiance at 7 visible wavebands.
- Validating satellite-derived ocean color products by comparing them with in-situ downwelling irradiance at 490 nm from drifter locations.
- Analyzing coastal upwelling patterns by examining time-series of location and temperature data from mobile buoys.
- Studying bio-optical relationships using concurrent measurements of surface irradiance and radiance across multiple spectral bands.
Strengths
- Includes multi-spectral optical data with 7 specific wavebands for upwelling radiance.
- Provides concurrent geospatial (location) and physical (sea surface temperature) parameters.
- Covers a defined 10-month temporal range from June 2000 to March 2001.
Limitations
- Temporal coverage is limited to a single, non-continuous 10-month period.
- Geographic scope is restricted to the coastal regions of California and Oregon.
- Sample size and data resolution (e.g., row count, sampling frequency) are unspecified.
