EarthCare Underpass#

HALO-20240813a underpass distance 31 m at 2024-08-13T15:39:53.0 s

Impressions#

(itemized list of things you saw)

  • north of the ITCZ edge shallow clouds were overlayed by a heavy dust layer. Cirrus clouds aloft.

  • about 138 nm from SAL there was an abrupt drop of about 5mm in the PW

  • EC meeting point at 15:41:30 UTC on slightly lower FL360

  • passing by the northern circle on the EC track there are very calm surface winds obvious from a narrow sun glint spot in specMACS and high radar reflectivity from the surface at around 15:55 UTC

Note

Co-location with ATR and EarthCARE over an aerosol layer near SAL. Spectacular line of convection on southern edge toward the west.

Dropsondes

50 sondes in total, 1 on the EC track and 49 sondes distributed over 4 circles with 1 launch detect failure in `c_north`

HAMP

no entry

PI-Camera

MM-DD:hh:mm:ss reset based on Bjorn’s watch (within 1s of Bahamas time) betwen DSC_6548 and DSC_6549, year inadvertently set to 2019

Smart

Upper sensor was fixed and the downward irradiance Fdw has to be corrected. For quicklooks the offset angles have been approximated so Fdw has to be regarded as preliminary.

SpecMACS

Nadir measurements started about 20 min after takeoff due to temperature issues. Some ice on one of the side cameras just before it got dark. Measurements stopped at 20:30 UTC due to darkness.

VELOX

VELOX fully functional; KT-19 affected by condensation
