As reported on the SWPC website (swpc.noaa.gov) Solar Cycle 25 has begun. Quoting: "The solar minimum between Solar Cycle 24 and 25 - the period when the sun is least active - happened in December 2019, when the 13-month smoothed sunspot number fell to 1.8, according to the Solar Cycle 25 Prediction Panel, co-chaired by NOAA and NASA. We are now in Solar Cycle 25 with peak sunspot activity expected in 2025."

SuperDARN PI Dr. Jiaojiao Zhang has passed on the news that two radars are under construction at a site in Inner Mongolia. The build is part of the Meridian Project phase II and follows the inauguration of the first SuperDARN radar in China at a site near Jiamusi (http://vt.superdarn.org/tiki-read_article.php?articleId=354). This will be a twin radar site. The photo shows the construction of one of the antenna arrays. A total of six radars are planned to be built as a chain across northern China. Jiaojiao has been assisted in this work from the beginning by her colleague Dr. Ailan Lan.

Congratulations to Dr. Zhang and her team at the National Space Science Center (CAS)!

During the 2020 SuperDARN workshop held online the SuperDARN Executive council welcomed a new group from the National Space Science Center (NSSC), Chinese Academy of Sciences (CAS) to the collaboration and voted the PI of the Jiamusi radar, Dr. Jiaojiao Zhang, to council membership.

The Jiamusi radar, also known as AgileDARN, features new kinds of digital control electronics and has been providing data to the SuperDARN data flow since mid-2019. The radar increases SuperDARN coverage at mid-latitudes in the east Asian Sector. First results were reported by Zhang et al. (2020), see 'Read More' for bio details.

Congratulations to Dr. Zhang and her team at the NSSC!

Grid2, map2 files available back to July 2006

By: ksterne  on: Fri., Apr. 17, 2020 11:08 AM EDT  (1092 Reads)
As a general update, it's been a few years since the major revisions to our grid- and map-level processing software were complete. These revisions date back to RST 4.0 (as of this writing, RST is at version 4.3.1) with the new files being named grid2 and map2 so that previous files could be maintained for data reproducibility. A number of other data issues were being sorted out and processed, including the expansion of the VT data storage systems, that delayed a mass processing of the new files. However with a break in some activities, grid2 and map2 files have now been generated back to the start of the modern dmap file format on July 1, 2006.

As always, for a listing of what files we have for certain dates please visit our Data Inventory page.

Marina Schmidt of the University of Saskatchewan SuperDARN group has announced the official release of pyDARN. In her words
'pyDARN is a python library used for data visualization of SuperDARN data.
Currently, it can:
- read and write SuperDARN DMap files
- read, write and convert Borealis hdf5 files
- range-time parameter plots
- summary plots
Thank you for all the support and help from the community.'
