2. Outline Background Objective Research components Recent progress and preliminary results Future work . 3. Background NASA has classified tropospheric wind profiling as high-priority science and invested in wind profiling instrument development efforts. It is anticipated the future Doppler wind lidar (DWL) measurements could be helpful for both seasonal climate studies and high-impact weather forecasting Objective Under a NASA supported research project, our main9460

5. 5 Figure shows the 20-year mean wind and vector differences between two reanalysis (left panels). Right panels show the mean wind and vectors from NCEP reanalysis. Due to lack of wind observations (such lack of constrain to the analysis from the data) , the reanalysis tends to be different due to the use of different models.
