ALMA weather station network
In September 2015, ALMA has deployed 6 weather stations in addition to
two central stations in order to assess their use in improving antenna
position measurements in large configurations. Below is a movie
showing the differential barometric pressure and winds during a 19-day
period in late October 2015. A logarithmic polar plot is employed in
order to compress the distances involved. The azimuthal tick marks are
spaced by 1 km. Large mountain features are denoted by grey ellipses.
The effective daytime periods (9AM-9PM) are
distinguished with a pale yellow background. Data from the APEX
and ASTE telescope stations are also included.
