ACE-1: Discoverer Spectroradiometer Measurements (300-598nm) (Johnson)


This dataset contains spectroradiometer measurements (300 to 598 nm) collected aboard the NOAA R/V Discoverer by James Johnson (NOAA/PMEL) during the ACE-1 cruise. A Licor 1800 Spectroradiometer with an 8 nm bandwidth was used to measure spectrally resolved solar irradiance. This data contains day of year in UTC (decimal of 15-minute averages), and data at 2 nm intervals (from 300 to 598 nm) in units of watts/meter-2/nm. This dataset was processed and quality controlled by PMEL.
