Description

Total column nitrogen dioxide measured measured during DANCE cruise HRS1414 aboard the R/V Hugh R. Sharp from July to August 2014 on the offshore Mid-Atlantic Bight and northern South-Atlantic Bight between latitudes 31.60°N and 38.89°N and longitudes 71.09°W and 75.16°W. Sampling procedures and methods are found in Martins et al. 2016. Data are not cloud screened. For cloud screening use columns rms_unweighted or rms_weighted and NO2_uncert.
