Global Climate Monitor

Global Climate Monitor is a GeoVisor that studies the effects of drought and changes in temperature and precipitation.

The Climate Research Group is a group of climate research at the University of Seville (US) interested in the spatial and temporal dimension of climatic variables and the interconnections between climate and society. Geographica develops for them Global Climate Monitor, a climate data Geovisor.

The goal of this group is the analysis and management of climate information, analysis of spatio-temporal climate variability and, finally, the study of climate impacts on society, namely, climate applications.

Climate Research Group relies on Geographica for the development of a climate data GeoVisor. Its objective is the study of patterns and effects of drought, as well as numerous analyzes of data sets temperature, precipitation and trends of recent years.

And so, Global Climate Monitor arises, a web viewer climate, global in nature, containing climate information recorded since 1901. This GeoVisor shows the variations of precipitation and temperature since the early twentieth century. The application displays information based on various climate parameters.

The Challenge:

The research group of the US needed a solution to display clearly and accurately the data obtained from its accurate reports. The experts had conducted numerous studies on climate resources (especially water and energy), and studies on climate risks, with special emphasis on drought.

There was a need to translate into a global map data obtained from research. Geographica should develop an accessible, intuitive and clear solution to allow visualization of the data and information generated by studies of the university group.

The Climate Research Group online GeoVisor needed to enable the visualization and analysis of data on a large scale and globally.

The Solution:

The British centre BADC (British Atmospheric Data Centre) and the Climatic Research Unit (CRU) of the University of East Anglia create and freely distribute climate data from more than 4,000 weather stations around the world.

This huge set of Open Data includes information on clouds, the series of average temperatures, the frequency of frost or the amount of rainfall, among other things. The data series begins in 1901 to register.

This is incomprehensible data source which uses the Research Group of the University of Seville to study the effects of drought and different patterns recorded.

To develop the Global Climate Monitor, several analyzes of the data were performed: Temperature (average, minimum and maximum), weather anomalies, and rainfall. It takes into account both annual and monthly periods.

Geographica introduce this data into a PostGIS spatial database, developed on open source database PostgreSQL. This creates an index with more than 90 million files, which confirms the success of working with PostgreSQL geospatial database.


Geographica has managed to develop a GeoVisor able to show a clear, intuitive and precise, the large amount of information from the databases of the Climate Research Group of the US.

The user can analyze and visualize large numbers of climate data. The map allows the possibility to compare the effects of climate anomalies in the world over the years.

Global Climate Monitor allows viewing and analysis of the evolution of temperatures and precipitation from 1901 to the present day. With these data, studies on the impact of climate on society and the effects of climatic changes undergone in the last century are encouraged.

GeoVisor online is available for anyone who wants to use it. This has been the work done by Geographica for Research Group at the University of Seville (Climate Research Group).
