[MIS01-P16] IT support to monitoring of greenhouse gases fluxes from the West Siberia bogs
キーワード：greenhouse gases fluxes, bogs, monitoring, information-analytical system
To meet the Paris Agreement objectives, one has to estimate anthropogenic and natural greenhouse gases sources and sinks. For West Siberia sinks and sources formed by bogs make quite significant input into a regional carbon cycle. To estimate relevant fluxes, and forecast global change impact on them, firstly one has to organize a bogs systematic monitoring, which leads to big archive and streaming data generations. Storage, analysis and its results delivery to stakeholders require development of relevant IT support. Reported are first results of development of a relevant information-analytical system “Carbon” aiming at monitoring and complex analysis of greenhouse gas fluxes for bogs ecosystems.
A prototype of the system consists of five key components: structured archives of spatial data and their metadata, digital shadow/twin of bog ecosystems based on PostgreSQL relational databases, computing core, a geoportal and GIS web client. The bog digital shadow/twin comprises PostgreSQL databases of measurement and modeling results describing its biological and geophysical characteristics, as well as relevant software components implementing REST API (application program interface) for accessing databases. It is integrated into the system using a developed middleware package. The middleware package consists of the following components:
1. Web access module that implements a unified REST API for accessing the digital shadow/twin as a single object. The use of the developed software allows a client to access the “digital twin” without going through the details of data structures on the server side, but to use conventional parameters for queries, such as, for example, the name of the geophysical quantity of interest (soil temperature, atmospheric humidity, carbon dioxide flux, etc.), the required level above the ground surface (height at 2 meters, surface, depth 30 cm, etc.), the time range and geographical area of interest.
2. Client software of the geoportal of the developed prototype of the system, consisting of the server side PHP application as well as client components implemented using ExtJS JavaScript library.
The figure displays a set of soil temperature average values for the November 2011 at the depth of 30 cm for various stations located in Tomsk region (background), and soil temperature daily means plot at the depth of 30 cm for the selected station (foreground) received by the geoportal (https://carbon.imces.ru/) using request to unified REST API developed.
This work is performed within framework of the IMCES project “System of carbon pools and fluxes monitoring of forest and bogs ecosystems of West Siberia south taiga zone”, which is a part of the key innovative project of national importance “The national system for monitoring the dynamics of climatically active substances in terrestrial ecosystems of the Russian Federation”.
