1-6 A6 OTIDES - Requests application and/or
adjustment of ocean tides. There are Colombo Model
two Ocean Tide models available in
GEODYN. First implemented was the
Colombo tide model and unnormalized
Legendre polynomials. M and K
symmetry is NOT included.
The presence of a RAYTID option
before the OTIDES cards invoques the
Doodson Ocean Tides. Immediately
following there is a description of the
Colombo model. At the end of this page
there will be a descrption of the Doodson
model.

This document contains the complete list of GEODYN OTIDE cards. If a Doodson
number does not appear on the printed tables, then GEODYN cannot model the tide
associated with that Doodson number.
UNITS: KM =Kilometers; M =Meters ; S =Seconds ; Kg =Kilograms
DEG=Degrees ; RAD=Radians ; AS =Arc seconds; MAS=Milli-arc seconds
IF CARD OMITTED: The ocean tide model is not used.
OCEAN TIDE MODELING
Ocean tide modeling in GEODYN is accomplished using the OTIDES option.
The following explanation will assist the user in invoking specific
tides and describes in more detail the implementation of the "tidal
families" within GEODYN. The ocean tidal constituents are divided
into two categories: Those major tides which (a) do and those which
(b) do not have significant sideband constituents. The sidebands are
long period modulations within a narrow band of the main tide lines.
For the 18 tide lines identified by GEODYN as having significant
sidebands, under the assumption that the admittances can be treated
as identical for near-by frequencies, GEODYN used linear admittances
to provide for the sideband tides within these so-called "tidal
families" if requested. When column 23 is set to 1 on the OTIDES card,
every degree and order element specified for the mainline tide causes
inclusion of the same harmonic for all of the corresponding sideband
tide lines in both the surface height and force modeling calculations.
However, if the tide line is not recognized by GEODYN as having
significant sideband contributions, a 1 in column 23 will be ignored.
Since the linear admittances are computed using the ratio of the
Doodson coefficients of the sidebands with respect to the mainline,
the Doodson ceofficients shown in the following tables indicate the
relative importance of the sideband terms within the total tidal
family.
The following tables describe the ocean tidal constituents
available within GEODYN. Tables 1, 1.1, 1.2, and 1.3 present
tidal constituents which have no internal tables containing sideband
terms. Therefore, even if the option flag in column 23 is set
to 1, no sideband modeling will be invoked. Table 2. lists the most
important tides commonly used in orbit modeling which fall within this
category. Tables 3, 3.1, 3.2 and 3.3 present the 18 tidal families
which can be invoked using the "family option" (column 23 set equal to
1 on the OTIDES card). Shown within these tables is the mainline tide,
the default sidebands which are included, and the terms in the angular
arguments defining the tide which modulate the mainline angular
argument.

COLUMNS FORMAT DESCRIPTION DEFAULT VALUE & UNITS
1-6 A6 OTIDES - Requests application and/or
adjustment of Doodson ocean tides . Colombo Ocean Tides
7-8 I2 Indicates sign term of the expansion:
+1 = prograde tide
-1 = retrograde tide
9 I1 Forcing degree in tide operating potential
(2 or 3). The order is the first integer in
the Doodson number given in columns 18-24.
10 I1 Inteder number [0,...,3] gives phase increment
after x{pi/2}. Useful when all tides use cosine
factors with positive amplitudes.
11-12 I2 Response degree of A,B coefficients.
13-14 I2 Response order of A,B coefficients.
15 I1 Paramater type index
=0 Ocean tide coefficient
=1 Atmospheric Tide coefficient
16-17 I2 Integer Flag:
=0 no sidelines
=1 turn n sidelines with input
tidal constituent.
=2 turn n sidelines with input
