In this lecture, Dr. Qian will provide an introduction to optical payloads in space missions. He will briefly describe six kinds of optical payloads, including hyperspectral imagers, multispectral imagers, Fourier transform spectrometers, lidar and active sensors, radiometers and spectrometers, and other type optical sensors.

Hear from experts across academia and industry that are working to monitor and mitigate greenhouse gas emissions. We will discuss the unique domain of remote sensing of methane emissions, it's challenges and limitations, and how we need to work together to push mitigation forward.

Synthetic Aperture Radar remote sensing has become a game changer in monitoring our planet at high spatial and temporal resolution. Because of cloud penetration of microwaves, ground observations at every SAR satellite overpass are nearly always available. This provides new insights into planetary change from novel temporal and spatial SAR signatures of natural and man-made targets. Mature SAR processing pipelines lead to Analysis Read Data (ARD) that can be coupled with modern tools to visualize and analyze these high-dimensional remote sensing data sets. Examples from a Global Coherence and Backscatter Data set and SAR Time Series Backscatter visualization are provided.

In this presentation, analysis of data the first three years of ROHP operations are presented. The ROHP calibration has been performed using data co-located with independent information from the NASA/JAXA Global Precipitation Mission (GPM) precipitation products and ionospheric activity. For a PRO observation, the induced cross polarization represents a cumulative effect from aspherical hydrometeors encountered anywhere along the propagation path. Analysis of ROHP data exhibit not only depolarization from the liquid phase (oblate-shaped rain) precipitation hydrometeors, but also positive differential phase signatures into and well above the freezing level, indicating possible sensitivity to frozen hydrometeors and the cloud vertical structure. These findings suggest the use of PRO data for evaluating of the representation of convection precipitation and moisture in global weather and climate models.

Continuous monitoring of the wind over vast ocean areas by airborne and satellite microwave scatterometers and reflectometers is essential for weather forecasting. The basic idea of the techniques relies on the assumption that the ocean surface normalized radar cross section (NRCS) (for both mono-and bi-static geometries) is correlated with the local surface wind vector.
