Observation System Simulation Experiments
Observing System Simulation Experiments (OSSEs) are observing system impact assessments providing objective quantitative evaluations of future observing systems such as a Doppler wind lidar (DWL). These experiments conducted at NOAA NCEP and NOAA AOML use "nature runs" from ECMWF (global) or AOML WRF (mesoscale) as plausible atmospheres for all simulations of DWL winds, cloud motion wind vectors and ocean surface vectors. Coherent, Direct Detection and Optical Autocovariance wind lidars concepts have been simulated for OSSEs.

DWL Operations within a Sensor Web Modeling and Data Assimilation System
A "Sensor Web Simulator" (SWS) was developed at NASA/GSFC for use in Earth Science mission planning. The SWS demonstrated how advanced information technology can reduce mission costs, extend mission life, and enable better data collection through the collaboration of observing system assets and numerical models. The SWS focused on three potential Decadal Survey missions: the "3D Winds" mission, Extended Ocean Vector Winds Mission (XOVWM) and the Precipitation and Allweather Temperature and Humidity (PATH) mission. Also included was The Geostationary Operational Environmental Satellite R-series (GOES-R) mission.
