Abstract:

This dataset contains the outputs from assimilating MLT wind observations from ground-based Super Dual Auroral Radar Network (SuperDARN) and meteor radar networks into the Whole Atmosphere Community Climate Model (WACCM) using the Ensemble Adjustment Kalman Filter (EAKF) within the Data Assimilation Research Testbed (DART). Two Observing System Simulation Experiments (OSSEs) were conducted for the 2018/2019 Northern Hemisphere winter. In the first OSSE, Experiment 09, synthetic observations of lower atmospheric state variables and SABER and MLS neutral temperatures are assimilated. In the second OSSE, Experiment 10, additional synthetic ground-based MLT wind measurements were assimilated to assess their added value. An older version of the Experiment 08 has been deprecated. If access to Experiment 08 is needed please contact GDEX team.

The data includes the hourly output of the ensemble mean of prior neutral temperature, neutral zonal wind, and neutral meridional wind as well as the synthetic observation files.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in GDEX citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
