The primary purpose of this data set is to provide high resolution meteorological data and related surface geological and vegetation data for natural (e.g., uncultivated) desert sites where wind is or has been a major erosive or depositional force. The objectives are twofold: (1) to provide the detailed field measurements needed to carry out quantitative studies of wind as an agent of surface geologic change; and (2) to establish a baseline for defining the " normal" range of climatic conditions that can be expected to occur on a decadal time scale, in areas considered representative of the major American deserts. The Gold Spring locality was selected to represent that part of the Great Basin Desert that extends into northeastern Arizona. The long- term goal for acquiring and analyzing the Desert Winds Project data is to use them to address problems of land resource degradation by wind, whether resulting from climatic variation (aridification) or human activities (desertification), or both.

If the station is operating but transmissions are not received (missing), the precipitation sensor is recording data at the site. Once the tranmission problem is fixed and data are received, the cumulative precipitation value recorded is correct (although day and time associated with the rainfall is lost).

| Data format: |
Daily records of Gold Spring GEOMET station data from
19791027 through 19921231
in format binary
(version 0)
The binary format is provided to enable the data to be
stored and accessed on systems with smaller capacity,
and to speed retrieval of information from the files.
No files in the binary format are provided on the CD-
ROM. The binary file format is as follows:
The first four bytes of the data files are used as a signature to identify the file format. Signature bytes are interpreted as follows: byte 0: 'D' for "Desert" byte 1: 'W' for "Winds" byte 2: 'b' if the file is binary, 'a' if ASCII byte 3: format version number and byte ordering scheme:If file is ASCII, version number is a numeral '0' through '9'. If file is binary, the high-order bit indicates the byte ordering scheme of the data, and the rest of the bits indicate the version number. If the high-order bit is set, the data are MSB- ordered ("big endian"); the high-order byte of a two- byte word is stored in the low-order address. (e.g. Macintosh, SUN) If the high-order bit is clear, the data are LSB- ordered ("little endian"); the low-order byte of a two- byte word is stored in the low-order address. (e.g. Intel, VAX) The version indicator in the file format allows up to ten varieties of files to be read and written by the low-level data handling routines. Only version 0 is presently supported. Following the four-byte signature, the GEOMET station location is given as degrees, minutes, and seconds latitude encoded as two-byte two's complement binary integers followed by degrees, minutes, and seconds longitude encoded the same way. Data records are fixed-length binary records each containing 17 two-byte unsigned integers as follows: 01. Year 02. Day 03. Minute of the day, i.e. hour times sixty plus minute 04. Humidity times 100 05. Precipitation times 100 06. Barometric pressure times 1000 07. Wind direction times 100 08. Wind speed at 6.1m times 100 09. Peak gust at 6.1m times 100 10. Wind speed at 2.7m times 100 11. Wind speed at 1.2m times 100 12. Peak gust at 1.2m times 100 13. Air temperature at 6.1m plus 50, times 100 14. Air temperature at 1.2m plus 50, times 100 15. Soil temperature at 4cm depth plus 50, times 100 16. Soil temperature at 10cm depth plus 50, times 100 17. Soil temperature at 20cm depth plus 50, times 100Note that if the byte ordering indicated by the file signature is little-endian, all of the two-byte quantities will be encoded least-significant byte first, but if the byte ordering is big-endian, the two- byte quantities will be encoded most-significant byte first.
