For this purpose, a monitoring system for analyzing surface strain using resistivity strain gauges has been tested. Strain is a function of stress, and it is known that stress affects the mechanical properties of geomaterials and can lead to the destabilization of rock slopes. However, stress is difficult to measure in situ. In industrial practice, resistivity strain gauges are used for strain measurement, allowing even small strain changes to be recorded. This setting of dataloggers is usually expensive and there is no accounting for the influence of exogenous factors. Here, the aim of applying resistivity strain gauges in different configurations to measure surface strain in natural conditions, and to determine how the results are affected by factors such as temperature and incoming solar radiation, has been pursued. Subsequently, these factors were mathematically estimated, and a data processing system was created to process the results of each configuration. Finally, the new strategy was evaluated to measure in situ strain by estimating the effect of temperature. The approach highlighted high theoretical accuracy, hence the ability to detect strain variations in field conditions. Therefore, by adjusting for the influence of temperature, it is potentially possible to measure the deformation trend more accurately, while maintaining a lower cost for the sensors.<\/jats:p>","DOI":"10.3390\/s23042237","type":"journal-article","created":{"date-parts":[[2023,2,17]],"date-time":"2023-02-17T01:32:56Z","timestamp":1676597576000},"page":"2237","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Rock Surface Strain In Situ Monitoring Affected by Temperature Changes at the Po\u017e\u00e1ry Field Lab (Czechia)"],"prefix":"10.3390","volume":"23","author":[{"given":"Ond\u0159ej","family":"Racek","sequence":"first","affiliation":[{"name":"Institute of Rock Structure & Mechanics, Czech Academy of Sciences, V Hole\u0161ovi\u010dk\u00e1ch 41, 182 09 Prague, Czech Republic"},{"name":"Department of Physical Geography and Geoecology, Faculty of Science, Charles University, 128 43 Prague, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Balek","sequence":"additional","affiliation":[{"name":"Institute of Rock Structure & Mechanics, Czech Academy of Sciences, V Hole\u0161ovi\u010dk\u00e1ch 41, 182 09 Prague, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0756-2175","authenticated-orcid":false,"given":"Marco","family":"Loche","sequence":"additional","affiliation":[{"name":"Institute of Rock Structure & Mechanics, Czech Academy of Sciences, V Hole\u0161ovi\u010dk\u00e1ch 41, 182 09 Prague, Czech Republic"},{"name":"Institute of Hydrogeology, Engineering Geology and Applied Geophysics, Charles University, Albertov 6, 128 43 Prague, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"V\u00edch","sequence":"additional","affiliation":[{"name":"Statotest, U Jezu 525\/4, 460 01 Liberec, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9969-4641","authenticated-orcid":false,"given":"Jan","family":"Blah\u016ft","sequence":"additional","affiliation":[{"name":"Institute of Rock Structure & Mechanics, Czech Academy of Sciences, V Hole\u0161ovi\u010dk\u00e1ch 41, 182 09 Prague, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1507","DOI":"10.1002\/esp.1836","article-title":"The Critical Role of Climate and Saprolite Weathering in Landscape Evolution","volume":"34","author":"Dixon","year":"2009","journal-title":"Earth Surf.
