IVM reprocessed for 2020 - 2021

Includes every day with a conjugate maneuver

Dr. Thomas Immel 0 265

A number of IVM data are reprocessed on days between Feb 7, 2020 and Dec 22, 2021 where conjugate observation periods are present. The long list of these data is noted below. This correctly flags the IVM data mid-manuever to be good. It is recommended that if one is interested in data obtained during these short periods of time that you work with the latest revision of the data where the data quality flag is correct. Watch for timestamps reflecting the reprocessing date in February 2022 and an increase in the revision number over previously available data. Zip files containing these data will be published by Feb 14.

TIEGCM Model for 2020, 2021 now available

Model runs informed by HME product

Dr. Thomas Immel 0 236

TIEGCM model runs that incorporate the MIGHTI measurements of winds and temperatures are now available on the ICON FTP site. These are run using lower-boundary forcing from the ICON Hough Mode Extension 4.1 product. They are available from Jan 2020 to August 2021, with more to come following the continued production of the 4.1 product.

The zipped NetCDFs are available here.

The Documentation for the TIEGCM 2.0 model is available from the NCAR/HAO site.

ICON Mission Operations Update #8 - New EUV Level 1 products and revised Level 2 retrievals

Level 2 version unchanged for now

Dr. Thomas Immel 0 390

The EUV Level 1 (L1) product containing EUV limb radiances has been updated to V3. This resolves primarily remaining issues with flatfielding. The Level 2 (L2) products are now re-run using these L1 inputs. The retrieval algorithm hasn't changed but the revision number has been indexed on the L2 products. This now extends the L2 products into 2021.

Mission Operations Update #7 - New Plasma Velocity products

IVM data now at version 5

Dr. Thomas Immel 0 286

New IVM Level 2 data (Version 5 of Product 2.7) are now available. This update improves the running correction for observed bias, using a measurement window that extends days into the future to inform the correction. As such, the data are released several weeks behind other products (2.2 and 2.4 for example) We recommend that users migrate to these products (available on the ICON FTP site) and review the documentation available here.
