The environmental changes occurring throughout the world have become the focus of global scientific research. The spectroscopic environmental monitoring technology can be used to obtain information about pollutants based on the optical absorption, emission, scattering, and atmospheric radiation transmission principles by establishing a characteristic factor fingerprint spectrum database and a quantitative analysis algorithm. Further, this technology can be applied to dynamically monitor the air quality as well as the fixed and mobile pollutant sources. The environmental spectroscopy monitoring technology, which can perform real-time and rapid monitoring at high sensitivities and large scales, has attracted considerable research attention. To date, several principal environmental monitoring technologies and systems have been established. These mainly include investigations and applications of the lidar technology, differential optical absorption spectroscopy, tunable diode laser spectroscopy, and Fourier transform infrared spectroscopy. Based on these technologies and systems, the acquisition, transmission, and sharing of monitoring information provides basic environmental information for the whole society, which promotes the development of the environmental quality assessment systems based on the monitoring data and provides the scientific basis for environmental management in China.

To obtain the lunar elevation with high accuracy, it is necessary to accurately estimate the pointing error of laser. During the on-orbit operation of the Lunar Orbital Laser Altimeter (LOLA), the laser pointing at night deviates from that during the daytime due to the large temperature difference between day and night. This study first establishes a theoretical model of the detector receiving energy when the spot deviates from the center of the receiving field of view. Then, it analyzes the theoretical relationship between the spot offset and relative received energy based on this model and puts forward an estimation method of laser pointing error based on spot energy. Subsequently, the energy data generated when LOLA passed through Aestuum region during the surveying orbit (12 months) is used and combined with the estimation method. Then, the laser pointing errors of LOLA at night in moon are estimated to be 140.62 μrad along the orbit and −413.17 μrad vertical to the orbit, which are consistent with the results derived from LOLA earth scanning experiment and orbital intersection altitude data.
