Welcome to the free ocean tide loading provider
September 26, 2016: New Tide Models.
As eagerly awaited in the user community, we have added FES2012 and TPXO8-Atlas to
the available range of Ocean tide models, thanks to the efforts of Machiel.
The computations are automatically forwarded to SEGAL at UBI/IDL in Portugal, so that the
receivers of the parameter files would notice as small changes as possible, and - if the machines
and their connections are working - none at all as regards basic user interaction and delivery.
As of yet, a few options won't work with the relayed jobs: There's no plot option and no live
job activity-and-queue report.
SEGAL is a facility at the University of Beira Interior and Institute Dom Luiz.
July 20, 2012: Time series from BLQ-files -
July 26, 2011: BLQ to
g-Software (Micro'g Lacoste) converter.
a converter script olgt.pl
(in perl v.5.8.8). To run it under MS Windows,
June 20, 2011: mGal is not an SI unit,
and the numbers in the BLQ
result files lack numerical resolution.
Thus a change in conventions was made:
Henceforth, if you select
Gravity, the results are presented in μm/s2.
However, you can select "mGal" if you still prefer that.

With the growing number of precise geodetic observations, the requests
for ocean tide loading values have increased considerably. Therefore,
this webpage has been created in the hope it will help the geodetic
community. Just select an ocean tide model, tick the required type of
loading, fill in the coordinates of the stations, give your e-mail
address and press the submit button. The program will check if it can
read your input and if so, it will calculate the values and send the
results to you by e-mail. The program will take about 5 minutes per
station. An example of the output in normal BLQ-formal can be found
while an example of the output in the new
can be found
