Abstract:
The NSF-supported research icebreaker Nathaniel B. Palmer operates year-round in support of the U.S. Antarctic Program, carrying out global change studies in biological, chemical, physical, and oceanographic disciplines. This data set consists of underway data from leg NBP0505 on the R/V Nathaniel B. Palmer. This leg started at Punta Arenas, Chile and ended at Punta Arenas, Chile.
Quality
ATTRIBUTE ACCURACY REPORT: The expected relative errors on the GOME-2 level 1b data products, except cloud parameters which are expressed in absolute values: * Sun-normalized nadir radiance error is 2.1 percent for UV and 1.4 percent for visible. * Absolute nadir radiance error 1.9 percent for UV 1.2 percent for visible. * Absolute sun irradiance error 1.7 percent for UV 1.0 percent for visible. * ... FPA wavelength calibration accuracy less than 0.04 pixel. * PMD wavelength calibration accuracy less than 0.07 pixel. * Effective cloud fraction: Global monthly average difference 0.0 in January and 0.1 in July. The standard deviation of the differences in absolute values is 0.1 for both months. * Cloud top pressure: Global monthly average difference 27 hPa in July and 36 hPa in January. The standard deviation of the difference 110hPa in July and 104hPa in January.

LINEAGE/PROCESS STEP: PROCESS DESCRIPTION: The level 0 to 1b processing comprises the calculation of geolocation parameters for the actual integration time of each measurement, as well as the conversion of the raw binary readouts on the level 1a data stream to calibrated radiance and irradiance data for both, the four main channel detectors and the two polarization measurement devices. Effective cloud fraction and cloud top pressure are also determined. Furthermore, calibrated measurements from the on-board calibration sources, and the sun and moon are available in the level 1b product.
