2013 IGRF-Corrected Total Magnetic Intensity (TMI) gridded data, Karonga Area, Northern Malawi, 9.69S-10.09S (2017, investigators Estella Atekwana, Jalf Salima, Leonard Kalindekafe)

IGRF-corrected Total Magnetic Intensity (TMI) data for the Karonga area of Northern Malawi between 9.69S-10.09S and 33.79E-34.09E. This processed airborne magnetic data set is a subset of a larger country-wide airborne magnetic data set acquired by the Geological Survey Department of Malawi in 2013. This data was acquired with a flight elevation of 80 m along NE–SW lines with spacing of 250 m. The tie lines were oriented NW–SE and spaced 5 km apart. The data was gridded at 50 m cell size using a minimum curvature algorithm. The data set is cited in Kolawole et al. (2017) in which it was used as part of the project called "Active deformation of Malawi Rift North Basin hinge zone modulated by reactivation of pre-existing Precambrian shear zone fabric". The data file is in netCDF grid format. Funding was provided by NSF award EAR 1009988. This data set is shared with other researchers for the purpose of research in Malawi only. The government of Malawi has to be acknowledged as the source of the data, and all research findings have to be shared with the Geological Survey Department of Malawi. Detailed information on the acquisition parameters for this data (e.g. magnetometer sensor used, acquisition dates, geophysical contractor etc.) can be obtained from the Geological Survey Department of Malawi.

马拉维北部卡隆加地区（9.69°S–10.09°S，33.79°E–34.09°E）的经国际地磁参考场（International Geomagnetic Reference Field, IGRF）校正的总磁场强度（Total Magnetic Intensity, TMI）数据。本预处理航空磁测数据集，是2013年马拉维地质调查局采集的全国性航空磁测数据集的子集。该数据以80米飞行高度沿北东-南西（NE–SW）测线采集，测线间距为250米；联络测线沿北西-南东（NW–SE）方向布设，间距为5千米。数据采用最小曲率算法格网化为50米像元尺寸的格网数据。该数据集被Kolawole等人（2017）引用，在该研究中，它被用作题为“受早前寒武纪剪切带构造组构复活调制的马拉维裂谷北盆地铰链带活动变形”的研究项目的一部分数据。数据文件采用netCDF格网格式存储。本研究受美国国家科学基金会（National Science Foundation, NSF）EAR 1009988号项目资助。本数据集仅可与其他研究者共享，用于马拉维境内的科研工作。需注明马拉维政府为数据来源方，且所有研究成果需提交至马拉维地质调查局。关于该数据的采集参数（如所用磁强计传感器、采集日期、地球物理承包商等）的详细信息，可向马拉维地质调查局咨询获取。
