Google Earth Engine——臭氧总量绘图分光仪（TOMS）数据集代表了过去25年中可用于监测全球和区域臭氧总量趋势的主要长期、连续的卫星观测记录

The Total Ozone Mapping Spectrometer (TOMS) data represent the primary long-term, continuous record of satellite-based observations available for use in monitoring global and regional trends in total ozone over the past 25 years. The data are produced by the Laboratory for Atmospheres at NASA's Goddard Space Flight Center. Version 8 TOMS data products include level 3 gridded data (1.0 x 1.25 deg). The Ozone Monitoring Instrument (OMI), aboard the Aura satellite (July 2004 - current), has a higher resolution (1.0 x 1.0 deg).

These data represent a merged ozone product from TOMS/EarthProbe, TOMS/Nimbus-7, TOMS/Meteor-3, OMI/Aura and USGS-interpolated data for dates with no data.

Additional TOMS and OMI information

臭氧总量绘图分光仪（TOMS）数据代表了过去25年中可用于监测全球和区域臭氧总量趋势的主要长期、连续的卫星观测记录。这些数据是由美国宇航局戈达德太空飞行中心的大气实验室制作的。第8版TOMS数据产品包括3级网格数据（1.0 x 1.25度）。Aura卫星上的臭氧监测仪器（OMI）（2004年7月-现在）具有更高的分辨率（1.0 x 1.0 deg）。

这些数据是由TOMS/EarthProbe、TOMS/Nimbus-7、TOMS/Meteor-3、OMI/Aura和USGS对没有数据的日期进行内插的数据合并而成的臭氧产品。
