Long time series of FCDR and TCDR. These enhancements can occur in several ways.
Another way is the direct application to retrievals to generate TCDRs and thereby improve ECV databases.
digitised all its customer account information and is electronically capturing new documents for a USD17bn statewide public-employee retirement system, serving over 180,000 active, retired and former employees of participating Texas counties and districts.
It was further noted that operational TCDRs
achieved generally high scores for metadata, user documentation, public access, and usage, whereas sometimes medium scores were seen for software readiness and uncertainty characterization.
They further segmented satellite-based CDRs into fundamental CDRs (FCDRs), which are calibrated and quality-controlled sensor data that have been improved over time, and thematic CDRs (TCDRs
), which are geophysical variables derived from the FCDRs, such as sea surface temperature and cloud fraction.
