First ECLAT progress meeting Results from ECLAT's first year plan are achieved. Data products from the SuperDARN (electrostatic potential patterns, number of radars that operated at the time, interplanetary magnetic field, etc.) will soon be uploaded to the Cluster Active Archive web page. Also, Cluster C3 footprints on 120 km above the ground, according to two different Tsyganenko models (1996 and 2005), for years 2001-2009 will be uploaded to the Cluster Active Archive. Identification of the Cluster boundary crossings has also been done successfully. The library of static solutions were run with GUMICS MHD simulation (http://gumics.fmi.fi/). The results were validated and they show that the runs were successful. Reliable baseline detection method for the equivalent current processing was still on-going at the time of the review meeting. Significant progress in this task had anyway taken place just before the meeting. FMI scientists had found a new approach for computing the baselines based on the six lowest harmonics of quiet day curves for each station. These harmonics are used to create a template which gives a smooth description for the daily variation in the baseline curve. The daily median values are used to determine the baseline level for this template. This way the baseline values can be adjusted so that they follow also the slower variations which typically appear in magnetometer data (secular, seasonal, and tidal variations and instrument drifts). |
