A) INTRODUCTION ------------ Waves experiment on Wind spacecraft carried electric dipoles to monitor radio noise of local and solar origin in the frequency range 4 kHz-14 MHz. Three receivers handle this spectral range: TNR (4-256 kHz), RAD1 (20-1,040 kHz), and RAD2 (1.1-13.8 MHz). Much of the data were obtained at the location of the 1st Lagrangian point (~ 240 RE). For more details of the spacecraft, experiment, and datasets, see Another usefull site, maintained by the investigator team, is B) DATA FILES AVAILABLE VIA HTTPS/FTP: ---------------------------------- SPDF holds several digital and graphic files from the WIND/WAVES experiment in the wind/waves directory, with the output files named as follows: Location of the CDF files: https://spdf.gsfc.nasa.gov/pub/data/wind/waves/wav_h1 Also available on CDAWeb for ASCII lists and spectral plots. CDF data are built from the IDL-Saved binaries, and cover the 4 kHz-14 MHz band in three segments: 4 - 256 kHz; 20 kHz - 1.04 MHz; and 1.1 - 14.0 MHz. (These IDL-Saved segments, known as TNR, RAD 1, and RAD 2 are described in the later paragraphs below). Digital RAD1 Files, IDL-saved binaries and ASCII. Location: rad1_idl_binary, rad1_ascii_compressed ------------------------------------------------- These are IDL-saved binary files at 1-min resolution. By "restoring" the files, a color plot of the spectra could be made. Each file covers a full day, and is a 2-dimensional matrix of 256 (logarithmically spaced frequency channels covering 20 - 1,040 kHz) x 1440 (minutes/day), providing the noise levels as multiples of daily minimum in each channel. There is also an extra row (#1441) which provides the minimum noise level for the day in each frequency band in mV/(sqrt(Hz)). Not all 256 channels actualy monitor at one time; only about 32 do, and the rest are interpolations. ("R1" in the file name stands for the RAD1 receiver). The directory also carries a plotting software (which we find to be satisfactory only on an X-terminal), named WAVESDSP.PRO which can be used for data from any of the three datasets (from RAD1, RAD2, and TNR). Digital RAD2 Files, IDL-saved binaries and ASCII. Location: rad2_idl_binary, rad2_ascii_compressed ------------------------------------------------- Same as RAD1, but with a single difference that this covers 1.1 - 13.8 MHz. Data are most popular for investigations of solar and CME HF-radio bursts. Digital TNR Files, IDL-saved binaries and ASCII. Location: tnr_idl_binary, tnr_ascii_compressed ------------------------------------------------- Same as RAD1, but with the exceptions that the frquency range is 4-256 kHz and is covered by 96 channels. Data is mainly of interest to the emissions in the heliosphere and are directly entered in units of mV/(SQRT(Hz)) Plotting S/W. (Name: WAVESDSP.PRO) ------------- This IDL program enables spectral plots of any of the datasets named above, i.e, TNR, RAD1, and RAD2. The program was developed by the PI, Dr. Mike Kaiser. Summary and Power spectra plots -------------------------------- Plots of summary and power spectra of local and solar noise as 3-min averages in the frquency range 4kHz - 14 MHz, as one file/day. Plots are in PDF, POstscript (PS), PNG and some GIF formats Dust Impact data. Location: dust_impact_l3 ----------------- Dust impacts measured by the Time Domain Sampler (TDS) electric field detector, part of the WAVES instrument suite. It has over 20 years of dust impact data (>100,000 individual dust impacts identified so far) allowing for long-term statistical studies. The data range from 1995-01-01 to 2016-01-01 and will be updated periodically. Notes: SPEDAS routine: /idl/general/missions/wind/waves/wi_tds_dustimpact_load.pro References: Malaspina, D.M., M.
