Does anyone know anyone at the NOAA ARL/who has anything to do with the NCEP/NCAR reanalysis data?

It looks like the 1948 and 1949 data have been mislabelled as 2048 and 2049 - noticed when running HYSPLIT trajectory models.

I've sent an email via the general NOAA research office, but not convinced it will get to the right people...

Volcanic ash as a source of nutrients: How the Hunga Tonga eruption affected ecosystems in the South Pacific

The eruption of Hunga Tonga-Hunga Ha'apai (HTHH) in January 2022 ejected about 2.9 billion tons of volcanic material into the atmosphere and across the South Pacific. In early 2022, a scientific expedition (GEOTRACES GP21) investigated the impact of this monumental event on the biogeochemistry of the South Pacific Gyre (SPG) surface waters.

It seemed like NOAA #HYSPLIT was getting all the cred for where the spy balloon came from, so here are some back trajectories made with FLEXTRA (https://flexpart.eu/wiki/FtAbout). Trajectories in 150--70 hPa (~ 13-18km) go from China to Montana, arriving 18:00 GMT (Similar for 15:00 and 21:00 GMT)
