Regional biases in absolute sea-level estimates from tide gauge data due to residual unmodeled vertical land movement

The only vertical land movement signal routinely corrected for when estimating absolute sea-level change from tide gauge data is that due to glacial isostatic adjustment (GIA). We compare modeled GIA uplift (ICE-5G + VM2) with vertical land movement at ?300 GPS stations located near to a global set of tide gauges, and find regionally coherent...

Validating time series of a combined GPS and MERIS Integrated Water Vapor product

Increased knowledge of atmospheric water vapor can improve weather predictions and is expected to reduce errors in products derived from GPS and (In)SAR data. At GPS ground stations Integrated Water Vapor (IWV) is estimated from the GPS signal delay with a high temporal resolution. The Envisat MERIS spectrometer obtains spatially dense IWV...
