=================================================================
INTRODUCTION:

These merges were created using the data in the NASA
ARISE archive (http://www-air.larc.nasa.gov/cgi-bin/ArcView/arise) as of March 1, 2016.
Files were created for ARISE flights 1-19 on the C130 aircraft.  Names of
the merge files are as:
	dataID_locationID_YYYYMMDD_R#[_comments].extension
		where dataID="arise-mrg60-c130" for 60-second merge on the C130 aircraft (note that the timestamp represents the start time of the merge interval)
	locationID="merge"
	YYYYMMDD=aircraft flight date
	R#=R0, R1, or appropriate revision number
	[_comments] = optional comments
	extension = ict

In addition, a "grand merge" has been provided.  This includes data
from all the individual merged flights throughout the mission.
This grand merge will follow the name convention above
(i.e. "arise-mrg60-c130_merge_20140901_R0_thru20141004.ict", with
the comment "_thru20141004" indicating the last flight date included).

If any portion of the averaging period contains a Limit
of Detection (LOD) value for a given measurement, the average
is marked with an LOD flag. For the merge, all missing data = -999999,
Lower LOD=-888888 and Upper LOD=-777777.

The merge is in the ICARTT format. Information on the LOD values
are included in the header of the individual flight merges.
This information is not included in the merges because
calculation varies from flight to flight and species to species.

In some cases, variable names have been amended (e.g. to clarify
the PI in the case of duplicate measurements).  Additionally,
units have been standardized throughout the merge.  See
below for the specific variable name or unit changes.

We welcome any comments and suggestions for making the
merges as user-friendly as possible.  Please direct any feedback
to Michael Shook (michael.shook@nasa.gov, 757-864-5793) with a cc to
Gao Chen (Gao.Chen@nasa.gov, 757-864-2290).

*The "Unit Conversion" field shows one unit "to" another unit contained in parentheses (e.g. "(degC to K)") if the units changed between
	the PI data and the merge file at all, even if just the case differs.  If the units of a variable changed but no conversion was
	necessary, the unit text was changed or clarified from that in the raw file (e.g. to standardize units across a variable/measurement type).
	Where the field is empty, no unit change was made from the raw file.
