UCVM z1,z2.5 for CCA06 with GTL, CVM-S4.26.M01

A little history (from Phil)

CVM-S4(cvms) -- velocity model with near surface gtl

CVM-S4.26(cvms5) -- improved cvms without the near surface gtl but with a new optional elygtl that can be enabled from a configuration option in the config file. Z range is from 0 to depth interval, which is 500m.

CVM-S4.26M01(cvmsi) -- improved cvms5 that when within the depth interval returns cvms values (ie, brought back the near surface gtl) and cvms5(the improved cvms) values otherwise.

CVM-S4.26.M01(cvmsi)

The GTL related flags and their default setting in cvmsi src code,

• ADD_ALT_GTL (set to 0)
• ADD_ROB_GTL (set to 0)
• ADD_TJ_GTL (set to 1)

• ADD_GTL (set to 0)

cvmsi has embedded vs30 gtl code but not turned on by default. Any change in the setting of the flag would require recompile and reinstall of libcvmsi.so.

But, it does not make sense to have both ADD_TJ_GTL and ADD_GTL enabled since the Zrange is overlapped and so ADD_TJ_GTL code always take precedence.

Script to build UCVM

Copy the script below to your home directory.

Replace <<YOUR_BUILD_LOCATION>> in the script and point to your big scratch location(either scratch1 or scratch2)

chmod +x script

and

source ./script

#!/bin/bash

export MY_TOP=<<YOUR_BUILD_LOCATION>>/scratch1

export TOP_UCVM_TARGET=$MY_TOP/TARGET_UCVM
export UCVM_SRC_PATH=$TOP_UCVM_TARGET/ucvm
export UCVM_INSTALL_PATH=$TOP_UCVM_TARGET/ucvm_install

rm -rf $TOP_UCVM_TARGET
mkdir $TOP_UCVM_TARGET

cd $TOP_UCVM_TARGET

Test your UCVM installation

setup your UCVM enabled environment,

source <<YOUR_BUILD_LOCATION>>/scratch1/TARGET_UCVM/ucvm_install/conf/ucvm_env.sh

Your $UCVM_INSTAlL_PATH is now set to <<YOUR_BUILD_LOCATION>>/scratch1/TARGET_UCVM/ucvm_install and your $UCVM_SRC_PATH is set to <<YOUR_BUILD_LOCATION>>/scratch1/TARGET_UCVM/ucvm

To check if your ucvm environment is setup properly,

which ucvm_query

Following command will show what is available in this UCVM installation,

ucvm_query -H

Using a test file from UCVM regression suite,

-118.0 34.0 0.0
-118.0 34.0 50.0
-118.0 34.0 100.0
-118.0 34.0 500.0
-118.0 34.0 1000.0

Calling ucvm_query to query cvmsi model and interpolate it with the taper algorithm,

ucvm_query -m cvmsi,elygtl:taper -f $UCVM_INSTALL_PATH/conf/ucvm.conf < $UCVM_INSTALL_PATH/tests/inputs/test_latlons.txt

should return,
