Note to CZ colleagues
With the CZO program officially ended in Nov 2020, measurements at the main Providence site of the SSCZO continue as part of the USFS Pacific Southwest Research Station. Measurements at the San Joaquin Experimental Range and Soaproot Saddle sites continue as part of NEON. The Shorthair site is being decommissioned, with the NEON Teakettle site providing relevant measurements.
For applications of our SSCZO to chart a sustainable future for California and beyond, please see our Center for Ecosystem Climate Solutions.
