Remedy 1: Operationalise processing and delivery for non-satellite reference measurements and satellite CDR Interim L2 products.
Copernicus Services, including the Climate Change Service, will provide information in close to real-time using global and regional reanalysis outputs, as well as satellite-derived products. For the validation of these products, both delivered with high timeliness, it is essential to have non-satellite reference measurements available for use in near-real-time, which is rarely the case today. There is a need to operationalise quality control and delivery of such data in the future to realise the potential benefits that fiducial reference measurements with characterised uncertainty offer.
Currently, many reference measurements are provided with specific delays due to requirements for certain quality-control measures to be applied. But in many other cases, delayed mode provision relates solely to network data policies and / or to data transmission protocols. The usage scenario for a Virtual Observatory within a Copernicus Service would likely need a close to real time availability of reference quality data streams to enable the assessment of very recent satellite-data products and the close to real time performed reanalysis. If the quality analysis and data provision for non-satellite fiducial reference measurements cannot be operationalised, leading to faster delivery, quality assessments of Copernicus products at short time scales shall remain of limited nature, reducing the value of the data for applications.
In addition, the timely operational delivery of satellite Climate Data Record Interim Level 2 products that are consistent with their long-term climatology also needs to be fostered to improve close to real-time reanalysis products and their validation. The validation of the Interim products could enhance the needs for non-satellite reference measurements as part of an operational validation set up.
Gap 1.10 where the remedy of it would enable the networks of reference measurements with better geographical distribution that can become candidate for operational quality control and data dissemination.
The remedies of Gap 1.10 and this gap can be realised in parallel.
Copernicus Services, including the Climate Change Service (C3S), will provide information in close to real time using global and regional reanalysis outputs, as well as satellite L2 products. These outputs are not always consistent with their own climatology, because input data are not produced with the same quality at real-time as they are in elaborated climate data records. The availability of so-called "Climate Data Record Interim Products" would remedy this problem by producing products with as high as possible consistency with the climatology, being based on automated satellite inter-calibration and careful quality control. These types of data records are emerging from operational satellite agencies, but lacks optimal means for validation due to non-availability of many non-satellite reference measurements in close to real-time.
