The winter of 2010 registered the most extreme negative value of the North Atlantic Oscillation (NAO) index since the beginning of systematic instrumental records. The anomalous pressure gradient in the North Atlantic region steered a large number of low pressure systems via an unusually southern path, directly influencing Iberia and northern Africa. Large areas of Iberia-especially […]

Uses of rainfall spectrum data
The scientific interest in rainfall spectrum (its drop size distribution, DSD) is double. On one hand it provides information about cloud physics and rainfall generating processes. On the other hand, the DSD controls relevant rainfall properties such as its kinetic energy (relevant for soil erosion studies), the reflectivity of microwaves (relevant for the remote sensing […]
SPEIbase, among the most downloaded items of digital.CSIC in 2010
The SPEIbase was one of the most downloaded items of digital.CSIC in 2010 in various formats. The raw version of the data base was the second absolute item with 13021 downloads since March 2010, while the plain text version was third with 11626 downloads. The netCDF version ranked 13th with 4012 downloads. Digital.CSIC is the […]
SPEIbase: A Global 0.5° gridded SPEI dataset
We have just made public a global drought dataset based on the SPEI (Standardized Precipitation-Evapotranspiration Index), for the period 1901–2006. I’m not giving much information here, because all the details are described in the SPEI base web site.
