NSSDCA ID: PSPA-00419
Availability: At NSSDC, Ready for Electronic Access
This data set was reformatted from the original BCD data set PSFP-00084 in December 2006 by NSSDC as part of the Lunar Data Restoration project. The data were put into CDF format for easier access and use. This data set contains hourly averaged plasma parameters (mainly of the solar wind) as observed on the moon at the Apollo 15 ALSEP site.
Four sets of hourly averaged parameters are computed, using as input data -- (1) all fine-time scale parameters (FTSP), (2) all FTSP computed from spectra with small rms error on curve fitting and thermal speeds less than one-half the bulk velocity, (3) all FTSP computed from spectra that satisfy the requirements of criterion 2 as well as having only one flow angle that can be directly measured, and (4) all FTSP computed from spectra that satisfy the requirements of criterion 2 as well as having both flow angles directly measureable. Contained in each of the 4 sets of averages are the proton density, alpha-to-proton ratio, bulk speed, angle of flow, number of spectra, and rms deviations of each average.
During the local lunar night there is no solar wind signal so there are data gaps of about 15 days each lunation.
The data set is available for user-selected plotting or data download at NSSDC's interactive CDAWeb site:
http://cdaweb.gsfc.nasa.gov/cdaweb/lunar/under the source "Apollo". The data are also available as PDS data sets, see:
