The first 11 Range Reference Atmospheres (RRA) listed were generated by the NASA Marshall Spaceflight Center (MSFC) with the coordination of the Range Commanders Council Meteorology Group beginning in 2019, as indicated by the file naming convention. They include the actual data in an Excel .xlsx file and a PDF report file. Data is produced for individual months and for the entire year grouped together (month 13).

RRAs with the * symbol were generated by the NASA/MSFC in 2013. RRAs with the # symbol were generated by the 14th Weather Squadron (14WS) in Sep 2006. Generally speaking, the POR for both the 2006 and 2013 cycles begins in approximately 1990. The POR for the 2019 cycle begins in approximately 1990 and generally extends through 2018. This POR was selected as detailed analysis of sample RRAs with longer PORs during the 2006 cycle indicated the potential of questionable data in the late 1970s and the 1980s. MSFC employed an automated quality control process and a manual process for suspect files. There is currently no plan to create RRA products for other sites. The next projected refresh cycle is 2024. Only files from the 2006 and 2013 cycles that were not created in the 2019 cycle have been retained.
