Airmass RGB - MSG - 0 degree

The Airmass product is an RGB (Red, Green, Blue) composite based upon data from infrared and water vapour channels from the SEVIRI instrument. It is designed and tuned to monitor the distribution of different air masses and evolution of cyclones, in particular rapid cyclogenesis, jet streaks and PV (potential vorticity) anomalies. Due to the incorporation of the water vapour and ozone channels, its usage at highest satellite viewing angles is limited. The Airmass RGB is composed from data from a combination of the SEVIRI WV6.2, WV7.3, IR9.7 and IR10.8 channels.气团产品是一款基于旋转增强型可见及红外成像仪（SEVIRI）的红外与水汽通道数据生成的RGB（红、绿、蓝）合成产品。该产品专为监测不同气团的分布及气旋演变过程设计优化，尤其可用于识别快速气旋生成、急流核以及位势涡度（potential vorticity）异常现象。由于纳入了水汽与臭氧通道数据，该产品在最大卫星观测角下的使用受到限制。气团RGB合成产品由SEVIRI的WV6.2、WV7.3、IR9.7及IR10.8通道的数据组合生成。
