Improving Archive Completeness and Timeliness of Data/Product Availability at Crustal Dynamics Data Information System (CDDIS)

Abstract:

The CoreTrustSeal is centered on the TRUST principles: Transparency, Responsibility, User Focus, Sustainability, and Technology. As a WDS regular member, the CDDIS meets the benchmark requirements set by CoreTrustSeal in supporting the geodesy community by archiving and distributing Global Navigation Satellite System (GNSS), Satellite and Lunar Laser Ranging (SLR and LLR), Very Long Baseline Interferometry (VLBI), and Doppler Orbitography and Radio-positioning Integrated by Satellite (DORIS) data and products. Although the CDDIS is already certified, it has continued to refine and make additions to improve its performance in meeting these metrics. With an ingest rate of 110k files/day supplied by 37 data providers and 41 product providers, the solution space is too large to solve without a proper, scalable piece of software. To address this problem, the CDDIS developed the Provider Upload Prediction (PUP) software which currently runs 2090 checks. This poster presents the software algorithm used to predict provider upload patterns, the methods used to alert providers of potentially missing data, and refinement over time.
