GOLD performs NI1 scans in both hemispheres from 17:00 to 21:00 hours \n\t spacecraft local time each night. NMAX is retrieved on a 2D rectangular (latitude vs. longitude) grid \n\t of fixed dimensions for each scan. However, the actual latitude and longitude values in the grid vary \n\t from scan to scan as the NI1 sequence utilizes a pattern of short (15 minute) localized scans that \n\t progress from east to west across the disk throughout the sequence.\n\t ", "Acknowledgement": "National Aeronautics and Space Administration; Dr. Richard Eastes", "Contact": [ { "PersonID": "spase://SMWG/Person/Richard.Eastes", "Role": "PrincipalInvestigator" }, { "PersonID": "spase://SMWG/Person/James.M.Weygand", "Role": "MetadataContact" } ], "InformationURL": [ { "Name": "GOLD Homepage web page", "URL": "https://gold.cs.ucf.edu/", "Description": "GOLD web page with news and other information." }, { "Name": "GOLD Missions Space Science Reviews Article", "URL": "https://doi.org/10.1007/s11214-017-0392-2", "Description": "Eastes, R.W., McClintock, W.E., Burns, A.G. et al.
