Abstract

The invention particularly relates to a distributed collaborative analysis system and method of massive climate pattern model output data. The system comprises a central server, a plurality of node servers, and at least one piece of Web front-end service equipment. The central server is used for storing global data information and node server information; the node servers are used for storing and managing node data information, performing task analysis scheduling management and data analysis processing; the Web front-end service equipment is used for user information maintenance, data information retrieval, task submission, analysis task status query and analysis result query and downloading. The data analysis work is finished at each node server, so that the data redundancy is reduced. The plurality of node servers are capable of collaboratively working, the contrastive analysis of the massive climate pattern model output data can be executed in a distributed manner, and an analysis result can be acquired on-line. Finally, the efficiency of the research work is greatly improved.

Description

technical field [0001] The invention relates to the technical field of data analysis and processing, in particular to a distributed collaborative analysis system and method for massive climate model output data. Background technique [0002] Earth system models are one of the most important scientific tools for global change studies. It uses numerical simulation methods to study the connection and evolution of the various layers of the earth, understand the past climate evolution process and predict possible future global climate changes. Models simulating different Earth system processes generate large amounts of output data. According to statistics, in The Program for Climate Model Diagnosis and Intercomparison (CMIP) of the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC). ), each model data center contributed more than 1.5PB of output data. Researchers need to conduct qualitative and quantitative comparative analysis of the output ...
