AQMET Air quality and meteorological measurements measured measured during DANCE cruise HRS1414 aboard the R/V Hugh R. Sharp from July to August 2014.

<p>AQMET Air quality and meteorological measurements 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.</p>

<p>Air quality and meteorological measurements were collected using commercial instrumentation. The data were averaged to 1 minute and spatial data were linearly interpolated to match the continuous 1 minute data.</p>

<p>Averages and data interpolation was done using MATLAB.&nbsp;Data during known periods of interference such as routine maintenance are reported as NaN. The NOx channel of the Thermo 42C failed during the campaign. NOx can be calculated using the NO measurement from the Thermo 42C and the NO2 measurement from the Aerodyne CAPS.</p>

<p>Complete sampling procedures and methods are found in Martins et al. 2016.</p>

本数据集为AQMET空气质量与气象观测数据集，采集于2014年7月至8月期间，由“休·R·夏普号”（R/V Hugh R. Sharp）科考船执行DANCE航次HRS1414期间获取，观测区域为中大西洋湾（Mid-Atlantic Bight）近海与南大西洋湾（South-Atlantic Bight）北部海域，纬度范围31.60°N至38.89°N，经度范围71.09°W至75.16°W。
本次观测采用商用仪器开展空气质量与气象数据采集。所有数据均被处理为1分钟分辨率的平均值，空间数据经线性插值以匹配连续1分钟时序观测数据。
数据平均处理与插值操作均通过MATLAB完成。已知存在仪器干扰的时段（如常规维护期间）的观测数据均以非数值（NaN）标记。本次观测期间，赛默飞42C（Thermo 42C）型分析仪的氮氧化物（NOx）通道发生故障，氮氧化物浓度可通过赛默飞42C的一氧化氮（NO）观测数据与Aerodyne CAPS的二氧化氮（NO2）观测数据计算得到。
完整的采样流程与观测方法详见Martins等人2016年发表的研究文献。
