Data Updates
NASA IceBridge POS/AV L1B Corrected Position and Attitude Data for Arctic 2013 are now available from NSIDC. For documentation, and to access the data, see the IceBridge POS/AV L1B data set landing page.
On 08 July, 2013, V01.1 data were replaced by V01.2. Data fields are revised in V01.2. For documentation, and to access data, see the IceBridge HiCARS 1 L2 Geolocated Ice Thickness data set landing page.
On 09 July 2013, the 2010 and 2011 Antarctica data were replaced with V01.1. For documentation, and to access data, see the IceBridge HiCARS 2 L2 Geolocated Ice Thickness data set landing page.
On 05 July, 2013, the V01 2009, 2010, and 2011 Antarctica data were replaced by V01.1. In the V01.1 data files, magnetic base corrections are removed and fields in the data files are re-ordered. For documentation, and to access data, see the IceBridge Geometrics 823A Cesium Magnetometer L2 Geolocated Magnetic Anomalies data set landing page.
On 05 July, 2013, the V01 2009, 2010, and 2011 Antarctica data were replaced by V01.1. V01.1 data files are revised in the Seconds field and the Laser Derived Surface field. For documentation, and to access data, see the IceBridge Riegl Laser Altimeter L2 Geolocated Surface Elevation Triplets data set landing page.
V01 data were replaced by V01.1. V01.1 data files include UTC timestamps and re-ordered fields. For documentation, and to access data, see the IceBridge BGM-3 Gravimeter L2 Geolocated Free Air Anomalies data set landing page.
On 31 January 2013 the ICESat Project Science Team announced that a correction to ICESat surface elevation data products is necessary due to an error in the range determination from transmit-pulse reference selection (centroid vs. Gaussian, G-C). Correction files and correction programs in FORTRAN and IDL are available via FTP. For more information about the findings and corrections please see Correction to ICESat Data Product Surface Elevations.
