Northern Cameroon daily interpolated rainfall, 1948-2022, combined dataset obtained via ordinary kriging

<p><strong>Description:</strong>&nbsp;This dataset provides daily interpolated rainfall maps for Northern Cameroon, including North and Extreme North provinces, for the period 1948-2022, at 0.01&deg; resolution, derived from daily rain gauge data observations.</p> <p><strong>Dataset Preparation Methods:</strong> This dataset was created by combining maps obtained by performing interpolation from daily rain gauge data (<a href="../doi/10.5281/zenodo.10156437">NoCORA - Northern Cameroon Observed Rainfall Archive</a> dataset) , using ordinary kriging with fitting of Circular variogram models and ordinary kriging with fitting of Spherical variogram models. The maps produced by the Spherical variogram models were taken as base of the combined dataset. Dates that could not be produced by the Spherical variogram models, but were produced by the Circular variogram models, were added to the combined dataset. Equally, dates produced by the Spherical variogram models containing negative values, but containing positive values when produced by the Circular variogram models, were replaced. The Mean Error calculated for both variogram models showed a similar bias and a paired t-test showed no significant difference. Resolution of interpolation is 0.01&deg;. The daily results were assembled into daily geotiff files.</p> <p><strong>Funding:</strong>&nbsp;This project was funded by the DESIRA INNOVACC project.</p> <p><strong>Authors Contributions:</strong></p> <ul> <li>Data treatment: Clara Knops.</li> <li>Documentation: J&eacute;r&eacute;my Lavarenne, Clara Knops.</li> </ul> <p><strong>Changelog:</strong>&nbsp;</p> <ul> <li>v1.0.0 : initial submission</li> </ul>
