This article highlights the availability of new sensor data from networks that have submitted data to IRIS Data Services during the fall of 2021 (Sept-Dec). Note that the actual data from these may not have been collected during 2021, just that they became available for the first time during this quarter. Newly collected data can remain restricted as defined by the data restriction policy. https://ds.iris.edu/ds/nodes/dmc/data/types/restricted
