SCM

SCM data products


The search coil magnetometer (SCM) is the one of the three EM field measurement payloads aboard CSES. It aims to measure the magnetic field fluctuation of low-frequency EM waves in the frequency range of 10 Hz to 20 kHz. the SCM data include three frequency band waveforms and/or power spectral density (PSD) data, i.e., ultra-low-frequency band (ULF, 10–200 Hz) data with a 1024-Hz sampling rate, extremely low frequency band (ELF, 200–2200 Hz) data with a 10.24-kHz sampling rate, and very low frequency band (VLF, 1.8–20 kHz) data with a 51.2-kHz sampling rate. The scientific data file uses the hierarchical data format (HDF), and their corresponding figures use the portable network graphics (PNG) format.
