Welcome to the online repository for RHESSI terrestrial gamma-ray flash data. Click here to access the database. The file 00_DOCUMENTATION.TXT, which should appear at the top of the list, is a guide to the rest of the data tree and file formats.

You can download a single gzipped tarfile of the database here.

A new experimental algorithm similar to the one devised by Gjesteland et al. 2012 (GRL 39, L05102) is finding a larger rate of events. It includes triggers at 60us, 100us, and 300us, which bring in a lot of shorter TGFs. On the other hand, 3ms, 10ms, and 30ms windows have not yet been able to find many new longer events. This catalog has an interactive map here. The TGFs can be sorted by many criteria and both studied on the map and downloaded as ASCII TGF lists. The underlying trigger algorithm is being refined, so if you use this catalog, note the date that you accessed it and contact us for the trigger parameters in use at that time. This project was developed by Paul Buzbee, a UCSC undergraduate who graduated in 2012.
