The typically weak cross-sections characteristic of Raman processes has historically limited their use in atmospheric remote sensing to nighttime application. However, with advances in instrumentation and techniques, it is now possible to apply Raman lidar to the monitoring of atmospheric water vapor, aerosols and clouds throughout the diurnal cycle.

Knowledge of cloud-base heights is important for climate studies, weather, and military operations. Conventional lidar methods monitor cloud depths by direct transmission of the beam through the cloud and sensing the backscattered returns. These techniques are limited by severe optical scattering by cloud particles to thickness <0.5 km. We have conceived of(More)
A complement of Readiness, Implementation and Management Plans (RIMPs) to facilitate management of post-launch product test activities for the official Geostationary Operational Environmental Satellite (GOESR) Level 1b (L1b) products have been developed and documented. Separate plans have been created for each of the GOES-R sensors including: the Advanced(More)
Laser vibration sensing provides a sensitive non-contact means of measuring vibrations of objects. These measurements are used in industrial quality control and wear monitoring as well as the analysis of the vibrational characteristics of objects. In laser vibrometry, the surface motion is monitored by heterodyne laser Doppler velocimetry, and the received(More)
This report describes calibration of the DMSP Special Sensor Microwave Imager Sounder (SSMIS) Lower Atmospheric Sounding (LAS) channels. SSMIS, shown in Figure 1, is a conically scanning microwave imager/sounder. It combines the functionality of SSM/I together with a number of new sounding features providing vastly increased altitude coverage, based on new(More)
A single-cavity solid-state laser that is resonant with sodium D(2) absorption is reported. Simultaneous 1.06- and 1.32-µm emission from a Q-switched Nd:YAG laser is summed with an intracavity type II KTP crystal. A single-intracavity étalon is sufficient to provide a time-averaged linewidth of 1.7 GHz at 589 nm.
