Prognoz-10 Data Files

Two sets of files of Zip-compressed ASCII data listings containing magnetic field and plasma data observations at 10-sec time resolution from the Prognoz-10 spacecraft are available for retrieval. The on-line selection currently contains ~5 months of data from mid 1985. Decompressed (i.e. ASCII text) data is also available for alternate viewing for a shortened 1-day file of Plasma for Apr 30, 1985 and for an 11-day file of Magnetic Field for Oct 23-Nov 3, 1985.

The files are accessible through the following hot spot:

Zip Data Compression Utility

All data files were compressed using the zip format. A freeware decompression application program, Unzip is available from the Info-ZIP workgroup which maintains this utility for a range of hardware platforms. Zip and Unzip are compatible with the DOS-based PKZIP by PKWARE, Inc.

For MacIntosh Netscape users, place your Unzip application program in your Netscape Helpers folder if you download it from the Info-ZIP workgroup site. When you click on the first GOES zip file, Netscape will inform you that it is does not know this format and will allow you to pick an application to interpret it. Choose Unzip from the Netscape Helpers folder. Afterwards make sure to set Unzip in Helpers of the General Preferences (Options pull-down) to have Mime type: application, Subtype: zip, Extensions: zip, File type: .zip, and optionally Action: Launch Application.

Data File Descriptions

Each Plasma file has a name of the form PLA_MMYY.zip where

MM is the two-digit month within the year of the data,
YY is the two-digit year of the data.

For example, PLA_0585.zip contains compressed 10-second Plasma data from the Prognoz-10 satellite for May, 1985. When a Plasma file is decompressed, each line within the resultant ASCII file contains the following items:

month,
day,
year,
hour,
minute,
second,
North/South flow angle (deg),
East/West flow angle (deg),
flux nv (10**6/cm**2-s),

A 31-day file of data will be approximately 1Mbyte in size.

Each Magnetic Field file has a name of the form MF_MMDDYY.zip where

MM is the two-digit month within the year of the data,
DD is the two-digit day within the month of the data,
YY is the two-digit year of the data.

For example, MF_052785.zip contains compressed 10-second Magnetic Field data from the Prognoz-10 satellite for the latter part of May, 1985. When a Magnetic Field file is decompressed, each line within the resultant ASCII file contains the following items:

clock (not of use),
Bx (GSE),
By (GSE),
Bz (GSE),
B,
day,
month,
year (2-digit),
hour,
minute,
second,

A 10-day file of data will be approximately 1.2Mbytes in size.
