RELEASE-2023

The Level 1 waveform data product is a geolocated slant-range waveform product where the return waveform is relative signal intensity versus 1 nsec time bins. The X and Y output coordinates will be reported as Easting and Northing values in a Universal Transverse Mercator (UTM) projection with the World Geodetic System 1984 (WGS84) International Terrestrial Reference Frame 2000 (ITRF 2000) ellipsoid horizontal datum with units of meters. The Z coordinates will be reported in a North American Vertical Datum 1988 (NAVD88) using the National Geodetic Survey Geoid12A height model with units of meters. The UTM zone will vary depending on the latitude/longitude of the specific NEON site. Each flight line will be saved as a Pulsewaves PLS and WVS file.

一级波形数据产品为地理定位斜距波形产品，其回波波形为以1纳秒时间仓为横坐标的相对信号强度分布。输出的X、Y坐标将以东向（Easting）、北向（Northing）坐标值的形式，采用通用横轴墨卡托投影（Universal Transverse Mercator, UTM），以1984世界大地坐标系（World Geodetic System 1984, WGS84）下的2000国际地面参考框架（International Terrestrial Reference Frame 2000, ITRF 2000）椭球作为水平基准面，单位为米。Z坐标将采用1988北美垂直基准面（North American Vertical Datum 1988, NAVD88），基于美国国家大地测量局Geoid12A大地水准面高模型计算，单位为米。通用横轴墨卡托分区（UTM分区）将根据特定NEON站点的经纬度进行调整。每条飞行航线将保存为Pulsewaves格式的PLS与WVS文件。仪器配置：NEON机载观测平台（Airborne Observation Platform, AOP）激光雷达（LiDAR）——Optech Gemini
