Description

Earth’s upper atmosphere is strongly affected by solar and geomagnetic activity and coupling to lower atmospheric layers, which together shape the properties of the rarefied gas encountered by satellites in low Earth orbit. Numerical upper-atmosphere models have limited predictive skill, but data assimilation can improve their simulations by combining them with satellite observations. Here we provide global simulations of the upper atmosphere for the full month of May 2024, including the extreme Gannon geomagnetic storm, as a supplement to a paper describing the TIE-GCM PDAF data assimilation software. The dataset demonstrates the software’s capabilities through a simulation without data assimilation and simulations that assimilate satellite-derived neutral mass densities from GRACE-FO 1 and Swarm-C. It includes gridded estimates of neutral mass density, neutral temperature, and electron density, along with simulated values at higher temporal resolution along the GRACE-FO 1 and Swarm-C satellite orbits and the files needed to reproduce the ensemble setup.

Expected crawler behaviour

Use a stable, truthful User-Agent with product/version and a working contact URL. Across all IP addresses and HTTP connections used by one crawler identity, allow no more than 5 requests in flight and wait at least 20 seconds between request starts. Crawl URLs listed in the catalog sitemap, including file pages and download URLs when they are published, use conditional requests, honor Retry-After, and apply exponential backoff after errors.

The welcome page may link to the interactive repository for human navigation. Automated clients must not treat that human link as a catalog crawl target.

Read the live machine-readable crawler policy before and during a crawl. Stop crawling when it reports CPU or memory utilization at or above 80% and 80% respectively.
