However, the extent to which these factors predict GPP response varies according to scales and land cover classes. Nitrogen (N) deposition has been highlighted as an important driver of primary production in N-limited ecosystems that also have an impact on biodiversity in alpine grasslands. However, the effect of N deposition on GPP response in alpine grasslands hasn\u2019t been studied much at a large scale. These remote areas are characterized by complex topography and extensive management practices with high species richness. Remotely sensed GPP products, weather datasets, and available N deposition maps bring along the opportunity of analyzing how those factors predict GPP in alpine grasslands and compare these results with those obtained in other land cover classes with intensive and mixed management practices. This study aims at (i) analyzing the impact of N deposition and climatic variables (precipitation, sunshine, and temperature) on carbon (C) fixation response in alpine grasslands and (ii) comparing the results obtained in alpine grasslands with those from other land cover classes with different management practices. We stratified the analysis using three land cover classes: Grasslands, croplands, and croplands\/natural vegetation mosaic and built multiple linear regression models. In addition, we analyzed the soil characteristics, such as aptitude for croplands, stone content, and water and nutrient storage capacity for each class to interpret the results. In alpine grasslands, explanatory variables explained up to 80% of the GPP response. However, the explanatory performance of the covariates decreased to maximums of 47% in croplands and 19% in croplands\/natural vegetation mosaic. Further information will improve our understanding of how N deposition affects GPP response in ecosystems with high and mixed intensity of use management practices, and high species richness. Nevertheless, this study helps to characterize large patterns of GPP response in regions affected by local climatic conditions and different land management patterns. Finally, we highlight the importance of including N deposition in C budget models, while accounting for N dynamics.<\/jats:p>","DOI":"10.3390\/rs11091135","type":"journal-article","created":{"date-parts":[[2019,5,13]],"date-time":"2019-05-13T05:35:39Z","timestamp":1557725739000},"page":"1135","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Studying the Influence of Nitrogen Deposition, Precipitation, Temperature, and Sunshine in Remotely Sensed Gross Primary Production Response in Switzerland"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8161-835X","authenticated-orcid":false,"given":"Marta","family":"G\u00f3mez Gim\u00e9nez","sequence":"first","affiliation":[{"name":"Remote Sensing Laboratories, Department of Geography, University of Zurich, Winterthurerstrasse 190, CH-8057 Zurich, Switzerland"},{"name":"Senckenberg Biodiversity and Climate Research Centre, Georg-Voigt-Stra\u00dfe 14-16, D-60325 Frankfurt am Main, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6919-0936","authenticated-orcid":false,"given":"Rogier","family":"de Jong","sequence":"additional","affiliation":[{"name":"Remote Sensing Laboratories, Department of Geography, University of Zurich, Winterthurerstrasse 190, CH-8057 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Armin","family":"Keller","sequence":"additional","affiliation":[{"name":"Agroscope - Institute for Sustainability Sciences Swiss Soil Monitoring Network NABO, Reckenholzstrasse 191, CH-8046 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9028-2205","authenticated-orcid":false,"given":"Beat","family":"Rihm","sequence":"additional","affiliation":[{"name":"Meteotest AG, Fabrikstrasse 14, CH-3012 Bern, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9627-9565","authenticated-orcid":false,"given":"Michael E.","family":"Schaepman","sequence":"additional","affiliation":[{"name":"Remote Sensing Laboratories, Department of Geography, University of Zurich, Winterthurerstrasse 190, CH-8057 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,5,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1623","DOI":"10.1126\/science.1097396","article-title":"Soil Carbon Sequestration Impacts on Global Climate Change and Food Security","volume":"304","author":"Lal","year":"2004","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1041","DOI":"10.1007\/s10021-005-0105-7","article-title":"Reconciling Carbon-Cycle Concepts, Terminology, and Methods","volume":"9","author":"Chapin","year":"2006","journal-title":"Ecosystems"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"785","DOI":"10.1002\/2015RG000483","article-title":"Spatiotemporal patterns of terrestrial gross primary production: A review","volume":"53","author":"Anav","year":"2015","journal-title":"Rev.
