Prefatry note: Environmental remote sensing and laser sensing
Global distributions of various environmental parameters are acquired in environmental remote sensing, mainly from the image analyses of both visible-infrared and microwave satellite images. Many of the studied variables are closely related to the issue of climate change, including the atmospheric concentra- tions of greenhouse gases, radiative properties of aerosols and clouds, water vapor and precipitation, changes in land surface coverage, sea surface temperature, and so on. By virtue of their superb character- istics of narrow bandwidth, good directivity, coherence, and high peak power, lasers can produce valu- able data when applied to environmental measurements. In this special issue, we present five review arti- cles that describe the topics of water vapor measurement in the oceanic troposphere, network observation of tropospheric aerosol, aerosol observation in the stratosphere, temperature and wind speed measure- ments in the Arctic mesosphere, and temperature and air density variations observed in the mesosphere over Antarctica, embodying the general versatility of lidar methodologies.
