Common use of TACs Clause in Contracts

TACs. In TACs in situ data are needed mainly for calibrating and validating satellite algorithms and products. In situ observations normally need higher quality, more comprehensive metadata and sometimes higher spatiotemporal resolution than for model validation. However, requirements for spatial coverage are not as critical as in the model applications. All data are offline. For interim reprocessed data, in situ data should be delivered within one month. Parameters: Tide gauge observations are needed to validate sea level gridded product (Level 4). Data from drifters and profiling floats are needed to derive currents for validating absolute geostrophic current derived from altimetry. More information about this dataset can be found in the PUM and QUID of the In situ TAC (▇▇▇▇://▇▇▇▇▇-▇▇▇▇▇▇▇▇▇.▇▇▇.▇▇/documents/QUID/CMEMS-INS-QUID-013- 044.pdf and ▇▇▇▇://▇▇▇▇▇-▇▇▇▇▇▇▇▇▇.▇▇▇.▇▇/documents/PUM/CMEMS-INS-PUM-013-044.pdf). The T/S profiles from Argo floats are needed to derive the steric sea level, for validating the altimeter total sea level. Quality: in situ sea level data should be provided with standardized format, similar to (Permanent Service for Mean Sea Level) PSMSL data, and also with quality flags. The FRM observations include:  Automated in-water radiometry from moored Fixed-Point Observatories  Automated above-water radiometry from Tower Fixed-Point Observatories  In-water radiometry from profiles acquired during dedicated research cruises  Inherent Optical Properties (IOPs) from profiles acquired during dedicated research cruises
