Magnetic anomalies, land and sea have been compiled by aid of satellite magnetic measurements to provide a public, overall picture of global distribution of magnetic anomalies originating from lithospheric sources (e.g. WDMAM 2007 and EMAG2. The present available image is incomplete both due to sparse coverage and variability of orginal reduction methods. Papers are solicited to present new data sets and reduction and compilation methods for magnetic anomalies of longer wavelength than 2 km, up to global scale. The aim is to promote compilation of the second edition of World Digital Magnetic Anomaly Map (WDMAM 2011)of the CGMW and IAGA. All contributions are welcome.
