APPENDIX I.
GENERAL NOTES
These General Notes should be consulted before utilizing any of the observational data
of this Appendix.
The General Notes describe the observational sites and instrument
. exposures on the various islets and at MACK, state the types of instruments used, and
give the procedures used in making shipboard observations.
Thus these Notes supple-
ment the far broader descriptions of the various islets given in the text.
The
Specific Notes for the individual tables, as listed in the Table of Contents, Appendix
I (preceding pages), should also be consulted before utilizing the data.
The Specific
Netes descrite departures from general observational practices as stated in the Genera:
Notes, give estimates of the reliability of the observations, and provide specific
comments that will be useful in interpreting the observational data.

The shelter, raingages, special anemometer, and the tower on which the regular
anemometer was located were all surrounded by barren ground composed of coral sand
and gravel.
The tower, however, was immediately adjacent to a surfaced taxi-way that
was an apron of the main runway.

HRaingages:
Standard 8-inch raingages were used at both locations 1 and 2.
Raingage 2 was located about 15 yards SW of a 2-story building and it was this gage
that was used for regular observations at the USAF weather station up until February 1,
1958.

The gage appeared to be in too sheltered a location with reference to the tradeand for this reason gage 1 was established at a distance of about 60 yards
from the building.
On February i this new location was adopted as the location of the
official gage, and effective that date there were rainfall readings only from this
