Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

  • Understanding the impact of geodetic measurements uncertainty on drought assessment: a case study of Europe   Order a copy of this article
    by Artur Lenczuk, Christopher Ndehedehe, Anna Klos, Janusz Bogusz 
    Abstract: A changing climate reveals that drought are becoming more severe and frequent, with cascading impacts on the environment, and people. As opposed to meteorological-based drought indices, GRACE and GPS observations have provided new capabilities and insights that improve understanding of drought dynamics. However, there are also limitations in the use of geodetic data. Thus, we examine the impact of GRACE and GPS residual errors on defined droughts estimating DSI and its uncertainty based on various approaches. Our results indicate the largest uncertainties above 35 degree. We observe a good spatial consistency in displacement uncertainties between GPS and both GRACE-type data for Western Europe, with relative RMS values over 20%. In comparison to original DSI, uncertainties contain 20% and 100% of DSI signal at 48% and 5% of stations for MSC JPL and GPS, respectively. For TCH method, we identify region-dependent hot spots and north-south strips for displacements and DSI, respectively.
    Keywords: global positioning system; GPS; GRACE; vertical displacements; DSI uncertainty; three-corner hat method; drought.
