CCS technologies are expected to account for the 20% of the CO<sub>2</sub> reduction by 2050. Geophysical, ground deformation and geochemical monitoring have been carried out to detect potential leakage, and, in the event that this occurs, identify and quantify it. This monitoring needs to be developed prior, during and after the injection stage. For a correct interpretation and quantification of the leakage, it is essential to establish a pre-injection characterization (baseline) of the area affected by the CO<sub>2</sub> storage at reservoir level as well as at shallow depth, surface and atmosphere, via soil gas measurements. Therefore, the methodological approach is important because it can affect the spatial and temporal variability of this flux and even jeopardize the total value of CO<sub>2</sub> in a given area.</p> <div> <p>In this sense, measurements of CO<sub>2</sub> flux were done using portable infrared analyzers (i.e., accumulation chambers) adapted to monitoring the geological storage of CO<sub>2</sub>, and other measurements of trace gases, e.g. radon isotopes and remote sensing imagery were tested in the natural analogue of Campo de Calatrava (Ciudad Real, Spain) with the aim to apply in CO<sub>2</sub> leakage detection; thus, observing a high correlation between CO<sub>2</sub> and radon (r=0,858) and detecting some vegetation indices that may be successfully applied for the leakage detection.</p> </div> <p> </p> </p></abstract><publication_date><month>02</month><day>03</day><year>2014</year></publication_date><pages><first_page>269</first_page><last_page>279</last_page></pages><publisher_item><identifier id_type="pii">gnest_01242</identifier></publisher_item><doi_data><doi>10.30955/gnj.001242</doi><timestamp>1714636082</timestamp><resource>https://journal.gnest.org/publication/gnest_01242</resource></doi_data></journal_article></journal></body></doi_batch> </div>
