NYCCAS Air Pollution Rasters

Citywide raster files of annual average predicted surface for nitrogen dioxide (NO2), fine particulate matter (PM2.5), black carbon (BC), and nitric oxide (NO); summer average for ozone (O3) and winter average for sulfure dioxide (SO2).

Description: Annual average predicted surface for nitrogen dioxide (NO2), fine particulate matter (PM2.5), black carbon (BC), and nitric oxide (NO); summer average for ozone (O3) and winter average for sulfure dioxide (SO2). File type is ESRI grid raster files at 300 m resolution, NAD83 New York Long Island State Plane FIPS, feet projection. Prediction surface generated from Land Use Regression modeling of December 2008- December 2019 (years 1-11) New York Community Air Survey monitoring data.As these are estimated annual average levels produced by a statistical model, they are not comparable to short term localized monitoring or monitoring done for regulatory purposes.

本数据集包含年度平均预测地表氮氧化物（NO2）、细颗粒物（PM2.5）、碳黑（BC）和一氧化氮（NO）浓度，以及夏季臭氧（O3）和冬季二氧化硫（SO2）浓度。数据文件采用ESRI网格栅格格式，分辨率为300米，基于NAD83纽约长岛州平面FIPS坐标系，采用英尺投影。预测地表数据源自2008年12月至2019年12月（第1年至第11年）纽约社区空气质量调查的监测数据，通过土地利用回归模型生成。由于这些数据为统计模型估算的年度平均水平，因此与短期局部监测或监管目的监测的数据不可比。关于NYCCAS设计和土地利用回归建模过程的详细描述，请参阅：nyc-ehs.net/nyccas。
