[MIS05-P05] Information-computational system CARBON as a tool for monitoring and analysis of greenhouse fluxes from the West Siberia bogs
Keywords:greenhouse gases fluxes, Web-GIS, bogs, information-computation system
To meet the Paris Agreement objectives, it is necessary to determine or at least to estimate anthropogenic and natural greenhouse gases sources and sinks on relevant territory. For West Siberia sinks and sources from 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. Also, it is necessary to have reliable data sets describing hydro-thermodynamic soil characteristics and greenhouse gases fluxes calculated on the base of a land surface model. Storage and analysis of those as well as its results delivery to stakeholders require development of relevant IT support. Reported are preliminary results of development of a relevant information-computational system “Carbon” (https://carbon.imces.ru/).
A prototype of the system consists of five key components: structured archives of spatial data and their metadata, digital shadow of wetland ecosystems based on measured characteristics, computing core, a geoportal and GIS web client. The bog digital shadow describes its instrumentally measured biological and geophysical characteristics, as well as the REST API (application program interface) for accessing databases are integrated into the system using a developed middleware package. The software is a tool for analyzing data describing hydrothermal characteristics, heat, moisture and carbon fluxes for bogs in the south of the taiga zone of Western Siberia. It comprises 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 delving into the intricacies of data structures on the server side, but to use well-known parameters for queries, such as, for example, the name of the geophysical quantity of interest (soil temperature, atmospheric humidity, carbon dioxide flux, and etc.), the required level relative to the ground surface (height 2 meters, surface level, depth 30 cm, etc.), the time range and geographical area of interest.
2. Client software on the geoportal side of the prototype of the system, consisting of a server application in PHP and client components implemented on the basis of the ExtJS JavaScript library.
Analyzed archives include data sets of calculations of the TerM land surface model, instrumentally measured characteristics data sets and open meteorological and climatic data sets.
The bilingual (Russian and English) CARBON portal provides an access to basic information about by the IMCES project “System of carbon pools and fluxes monitoring of forest and bogs ecosystems of West Siberia south taiga zone” as well as to the section “Analysis”, which is aimed at qualified users who are ready to perform calculations and interpret the obtained results. In particular, the section allows to use software for analysis of data sets characterizing the hydrothermal regime of the southern taiga zone of Western Siberia, as well as heat and greenhouse gas fluxes in the bogs of this region. The analysis is carried out on a personal computer with Internet access. The portal is constantly being developed, some changes in the interface are possible. To facilitate oneself with the web GIS system there is an open Demo version with limited functionality. To use it one has to select “Software” in the menu on the left and then select “Web GIS ‘Carbon 1.0 demo’”.
For full access to the portal data processing procedures, it is necessary to register by contacting the site administrator at webmaster@scert.ru and receive a login and password. After receiving the login and password one can authorize oneself by clicking on the “Guest” icon in the upper right corner of the window. One can familiarize oneself with the data sets and their specifications in the menu item “Technical specifications”.When conducting research and obtaining results using the Web GIS system “Carbon” (https://carbon.imces.ru/climate/), reference to the system is mandatory.
