Three tasks completed in this study are presented. 1 The climatologic model of scintillation index S4 map using the ROCSAT data during the moderate to high solar activity period is completed using the ROCSAT 32 Hz density fluctuation data collected at the 600 km altitude. The results are divided into two maps, one for strong scintillation S40.3 and the other, weak scintillation S40.3. 2 Study of coincident scintillation events between NCU-SCINDA data, COSMIC observations, and CNOFS observations. Since 2008-2009 are in the solar minimum period, not many scintillation observations were noted. In September 2009, SCINDA hardware and data acquiring software are malfunctioning so that no scientific data has been collected. Ron Catton, AFRL has been contacted to discuss how to remedy the situation. 3 Study of the outer-scale length of turbulence. Initially, the study started with a set of coincident observations made with the ROCSAT data and Ascension Island beacon experiment. The initial results are very encouraging and the study is continuing.
