DATA SERVICES UPGRADE: PERFECTING THE ISIS-1 TOPSIDE DIGITAL IONOGRAM DATABASEOVER THE YEARS THERE HAS BEEN A VAST AMOUNT OF FRUITFUL RESEARCH USING TOPSIDE IONOGRAM OBSERVATIONS FROM THE INTERNATIONAL SATELLITES FOR IONOSPHERIC STUDIES (ISIS) PROGRAM AND MORE RECENTLY FROM THE DIGITAL IONOGRAM FORMAT AVAILABLE FOR A SUBSET OF ALOUETTE-2 ISIS-1 AND ISIS-2 DATA. THE DIGITAL FORMAT ENABLED MORE THAN 100 000 ISIS-2 TOPSIDE VERTICAL ELECTRON-DENSITY PROFILES TO BE AUTOMATICALLY PRODUCED FROM THE DIGITAL TOPSIDE-IONOGRAM FILES USING SOFTWARE KNOWN AS TOPIST. THIS LARGE TOPSIDE ELECTRONDENSITY PROFILE DATABASE ENABLED SOME LARGE-SCALE STUDIES. TOPSIDE ELECTRON-DENSITY PROFILES DERIVED FROM THE ISIS-2 IONOGRAMS HOWEVER ARE LIMITED TO ALTITUDES BELOW 1 400 KM WHILE MANY INVESTIGATIONS NEED HIGHER ALTITUDE OBSERVATIONS. FOR EXAMPLE SIGNIFICANT DISCREPANCIES IN HIGH-LATITUDE TOPSIDE ELECTRON-DENSITY PROFILES ARE PRESENT BETWEEN THE INTERNATIONAL REFERENCE IONOSPHERE (IRI) MODEL PREDICTIONS AND THE TOPIST ISIS-2 RESULTS AND THE DISCREPANCIES INCREASE WITH INCREASING ALTITUDE. THUS THERE IS A STRONG NEED TO MAKE ISIS-1 IONOGRAMS WHICH CAN PROVIDE TOPSIDE ELECTRON-DENSITY PROFILE INFORMATION TO MUCH HIGHER ALTITUDES READY FOR LARGESCALE AUTOMATIC PROCESSING INTO ELECTRON DENSITY PROFILES. THE CURRENT ISIS-1 IONOGRAMS HAVE MAJOR DATA QUALITY PROBLEMS CAUSED BY DIFFICULTIES IN IDENTIFYING THE IONOGRAM FRAME SYNC PULSES AND FREQUENCY MARKERS DURING THE ANALOG-TO-DIGITAL CONVERSION PROCESS. AS A RESULT THE IONOGRAM FILES CAN CONTAIN PARTIAL IONOGRAMS OR MULTIPLE IONOGRAMS RATHER THAN A SINGLE IONOGRAM AND SINGLE IONOGRAM FILES WITH INCOMPLETE INCORRECT OR NO FREQUENCY INFORMATION. ALSO TO USE THE PRESENT ISIS-1 DIGITAL TOPSIDE IONOGRAMS EACH USER HAS TO INCLUDE SPECIAL TREATMENTS IN THEIR PROGRAMTO HANDLE SOME SPECIAL CASES INCLUDING FREQUENCY TREATMENT WITHIN CERTAIN RANGES WHICH IS A LARGE BURDEN AND PRONE TO ERRORS. IN THIS PROJECT WE WILL USE MATURE SOFTWARE TOOLS DEVELOPED BY THIS TEAM TO FIX ALL THE ABOVE-MENTIONED PROBLEMS WITH THE DIGITAL TOPSIDE IONOGRAMS AND SIGNIFICANTLY INCREASE THE TOTAL NUMBER OF VALID IONOGRAMS FOR TOPIST TO SUCCESSFULLY PROCESS. HERE WE PROPOSE TO USE THIS SOFTWARE TO REPROCESS ALL AVAILABLE ISIS-1 DIGITAL TOPSIDE IONOGRAMS FROM THE OTTAWA TELEMETRY STATION FROM 1969 TO 1983 WHICH COVERS MORE THAN A SOLAR CYCLE. WE EXPECT TO PROCESS AND MAKE READY FOR AUTO PROCESSING SOME 50 000 HIGH QUALITY ISIS-1 DIGITAL IONOGRAMS FROM THIS STATION. THE NEW DATA PRODUCT WILL BE ARCHIVED AT THE NASA SPACE PHYSICS DATA FACILITY (SPDF<HTTP://SPDF.GSFC.NASA.GOV>) AND MADE ACCESSIBLE AND SEARCHABLE THROUGH THE HELIOPHYSICS VIRTUAL WAVE OBSERVATORY (VWO<HTTP://VWO.NASA.GOV>). THE PROPOSED UPGRADE IN THIS PROJECT REPRESENTS A SIGNIFICANT IMPROVEMENT IN THE QUALITY AND UTILITY OF THE ISIS-1 DIGITAL TOPSIDEIONOGRAM DATA ITS FORMAT AND ITS ACCESSIBILITY. THIS DIGITAL TOPSIDE-IONOGRAM DATABASE WILL COMPLEMENT THE 35-MM FILM TOPSIDEIONOGRAM DATABASE BECAUSE THE ORIGINAL TAPES INCLUDED MANY THAT WERE NEVER PROCESSED INTO FILM IONOGRAMS. WE WILL FIX ALL THE PROBLEMS IN THE EXISTING ISIS-1 DIGITAL IONOGRAM FILES AND CREATE A NEW PRODUCT. THE RESULT WILL SIGNIFICANTLY IMPROVE THE DATAUTILITY AND ENABLE MANY IONOSPHERE/MAGNETOSPHERE INVESTIGATIONS E.G. THOSE INVOLVING THE PLASMASPHERE BOUNDARY LAYER I.E. THE PLASMAPAUSE VICINITY AND THOSE REQUIRING A SIGNIFICANTLY IMPROVED IRI MODEL FOR THE MID-TO-HIGH LATITUDE HIGH-ALTITUDE TOPSIDE IONOSPHERE.
