[IGSMAIL-8213] NASA MEaSUREs ES3

[Moore, Angelyn W (US 335G)]

Dear colleagues,

We would like to update you on SIO’s and JPL’s NASA MEaSUREs ES3
project, now in its third five-year cycle. We publish 4 levels of data
products building upon our daily displacement time series from a
combination of JPL and SIO GNSS solutions using common metadata from the
SOPAC database.

The daily time series and metadata can be viewed, coupled with a map
interface, on MGViz, our new single-screen user application
at MGViz.ucsd.edu (https://MGViz.ucsd.edu).

Our products are archived at SOPAC
(http://garner.ucsd.edu/pub/measuresESESES_products/)
and CDDIS (https://cddis.nasa.gov/archive/GPS_Explorer/archive/).

Please see the attached flyer and our Web pages at
sopac-csrc.ucsd.edu/index.php/measures-2/ 
(https://sopac-csrc.ucsd.edu/index.php/measures-2/)
for more information.  We have brief videos for MGViz and each product.

The products include:
(1)    Combined daily displacement time series for about 3500 regional
and global IGS stations, installed and maintained with geodetic quality
and well-documented metadata. We have two main products (with different
flavors trended, detrended, PCA-filtered, residuals).
•    The first is the result of extensive quality control and includes
unmodeled time series where non-physical displacements and poor-quality
data have been identified and corrected.
•    The second is a parametrically-fit time series, including slopes,
offsets, postseismic motions, seasonal terms, with uncertainties for all
parameters based on white and colored noise components.  Solutions for
the longest-lived stations begin in 1992.
(2)    A list of “problematic” stations that should be used with caution.
(3)    Weekly station velocities (for stations with more than 2.5 years
of data) and coseismic displacements.
(4)    Weekly 3-D displacement grids interpolated from the
median-filtered daily time series.
(5)    Weekly horizontal strain rate grids.
(6)    Modeled ETS transient events for Cascadia since 1994.
(7)    Water storage data for the Western U.S. since 2006.
(8)    5-minute troposphere delay estimates from 1992 and precipitable
water from 1995.
(9)    100 Hz seismogeodetic and 1Hz GPS displacement and velocity
waveforms for historical earthquakes.

A detailed document providing a description of our products with
underlying algorithms and theory can be found at

Please let us know any feedback, problem reports, or feature requests.
