Title:
Long-term groundwater-level anomalies across Sub-Saharan Africa (NERC grant NE/M008932/1)
code:
http://data.bgs.ac.uk/id/dataHolding/13607465
Abstract:
Multi-decadal time series of groundwater levels were compiled by the authors from records of observation wells initiated and maintained by government departments and research institutions in nine countries in sub-Saharan Africa. The pan-African collation of these hydrographs was initiated at the 41st Congress of the International Association of Hydrogeologists (IAH) in Marrakech (Morocco) on 14th September 2014. All records were subjected to a rigorous review by the authors during which the integrity, continuity, duration and interpretability of records were evaluated. This process included dedicated workshops in Benin, Tanzania, and Uganda, and records failing these tests were discarded from the analysis. Procedures included taking of the first time derivative to identify anomalous spikes in records commonly associated with errors of data-entry. Where multiple records in same geographic and climate zone were available (e.g. Benin, South Africa) we prioritized records remote from potential areas of intensive abstraction. Statistical clustering of records was also used in the Limpopo Basin of South Africa to identify the representativity of employed records at Modderfontein and Sterkloop.

Data Quality
Title:

explanation:
See the referenced specification
Title:
Commission Regulation (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services
explanation:
See http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2010:323:0011:0102:EN:PDF
statement:
Infilling of occasional gaps of less than a week in daily groundwater-level records was achieved by linear interpolation. Because permission to enable access to absolute values of groundwater levels and precipitation at all locations in this dataset has not been granted, both datasets are provided as anomalies with respect to the long-term value for the period of observation.
