ADT

AUTO

allows for automated ADT estimate utilizing NHC/JTWC forecasts and Laplacian analysis to objectively determine position of storm center

DEL

deletes history file record; must be used with DATE= keyword to define date/time limits

EDIT

edits contents of history file

LIST

lists contents of history file; see the Remarks

PLOT

plots a graph of intensity estimates from history file; see the Remarks

history_file

history file to be used (default=path defined in environment variable ODTHISTORY)

format

format of forecast file; the valid options are:

ATCF

tropical cyclone forecast records (default)

DISC

TPC WTNT4* or WTPZ3* storm specific discussions

PACWARN

JTWC WTPN3* tropical cyclone warning

GENERIC

see the Remarks for example format

fcst_file

file name containing forecast information for the AUTO option; the directory location is defined by environment variable ODTAUTO (no AUTOFIX)

day

adds comment to specified day in history file

time

adds comment to specified time in history file

comment

comment to add to history file for specified day and time

ATCF=

stormID sourceID rawT finalT
produces ATCF formatted listing for current ADT estimate or entire history file, or for portion of history file as defined by DATE= keyword (default=-1 XXXX 0 0), where:

stormID

annual tropical cyclone number and basin value, e.g., 10W, 06L; valid basin values are:
L=Atlantic
E=East Pacific
C=Central Pacific
W=West Pacific
A=North Indian Ocean
B=South Indian Ocean
S=Australian Region (90E-135E)
P=Australian Region (east of 135E)

sourceID

WMO identifier (e.g., NHC, PGTW, etc)

rawT

flag determining raw T number output; specify 0 or 1, where 0=adjusted raw T number, 1=unadjusted raw T number

finalT

flag determining final T number output; specify 0 or 1, where 0=6-hour weighted average, 1=3-hour straight linear average

the output file is created in the directory defined by the environment variable ODTOUTPUT using the naming convention CIMSS_DVTO_yyyymmddhhmm_ssbasin_FIX, where yyyy=year, mmdd=month (1-12) and day (01-31), hhmm=UTC time, ss=stormID, basin=sub basin

COLor=

CI MSLP T6hr T3hr AdjRawT UnAdjRawT 12hrAvgTIE CurrTIE outline text
defines graphic color levels of the PLOT option's plotted parameters; specify 0 to omit from display (default=1 2 0 0 0 0 0 0 6 7)

DATe=

bday btime eday etime
defines day and time range (from beginning day and time to ending day and time) for LIST, PLOT and DEL options; specify bday and eday in yyyymondd format (e.g., 2008SEP17) and btime and etime in hhmmss format (e.g., 131500)

DATAset=

source local
source and local ADDE datasets; specify as group/descriptor.position or alias.position, where:

source

identifies the infrared image to use as input for the ADT analysis (default=value defined by environment variable ODTLSERVE)

local

identifies the dataset to store the subsected image; the latitude and longitude location is determined by information in history_file (default=value defined by environment variable ODTLDATA)

DOMain=

defines domain for CI to MSLP conversion; valid options are ATL or PAC; see the Remarks (default=computed)

LAND=

YES

applies ADT land interaction rule (default)

NO

does not apply ADT land interaction rule

MAXWradius=

manually defines maximum wind radius in km; if the ADT estimate has determined an eye scene and a MAXW of less than 5 km is specified, the scene type will be changed to PINHOLE EYE; if a value of MAXW of greater than 45 km is specified, the scene type will be changed to LARGE EYE

OUTput=

loc file
defines destination of LIST option output, where:

loc

location to send the output; valid options are T, FILE and TFILE (default=T), where:
T - sends output to current text window
FILE - sends output to a file
TFILE - sends output to both current text window and a file

file

directory and name of file created by FILE and TFILE options; the default filename is ODTDUMP.ASC and the directory it is written to is defined by the environment variable ODTOUTPUT

OVERride=

YES

interactively overrides the automated scene type; cannot be used with AUTO option

NO

does not override the automated scene type (default)

RAWT=

overrides the initial raw T intensity classification value as defined by the subjective Dvorak rules; this keyword should be used only when analysis of a tropical cyclone is initiated at a time later than initial formation (storm has a raw T value greater than 1.0); if 0.0 is specified in this keyword, the value will be calculated by ADT (default=1.0)

SEARch=

YES

performs search for maximum curved band location if ADT estimate has determined a CURVED BAND scene (default)

NO

does not perform search for maximum curved band location

WIND=

YES

use with the PLOT option to plot its intensity values as maximum wind speed in knots rather than MSLP; speed and MSLP values are derived from the empirical relationship to CI number defined in Dvorak [1984] and Shwechuck and Weir [1980]

NO

plots the intensity values as MSLP instead of wind speed (default)
