Sierra Rotors was a joint NSF-funded project involving DRI, NRL, University of Washington, and NCAR. We thank all SRP participants for their individual efforts. DRI surface network has been built and is maintained in collaboration with the DRI Western Regional Climate Center. The objective analysis of the Sierra Rotors surface network data was done with the assistance of Ming Xiao, whose help is greatly acknowledged. Stephen Cohn and Bill Brown of NCAR are thanked for providing the wind profiler data and their interpretation for this study. Numerical simulations were run at the Mesoscale Dynamics and Modeling Laboratory (MDML) 68-processor Linux cluster, funded by NSF MRI Grant ATM-0116666. This work was supported in part by NSF Grant ATM-0242886.
