Subproject 2
Past and future hydroclimate

· WP3: Improving our description of recent past climate variability in La Plata Basin
The main objective of this WP is to improve the description of past
climate variability in LPB in order to provide an observational basis for
quantifying past climate variability (WP4 and WP6), evaluating climate
scenarios (WP4, WP5 and WP6) and providing high-quality data to WP7 for impact model calibration (WP8 and WP9) .

Specific objectives
· To build on the FP6 CLARIS daily database to create a spatially
highly-dense daily database (precipitation, min/max temperature,
radiation, vapour pressure) and to develop and implement an automated daily data homogeneization software for this large database.

· To ensure the sustainability of the CLARIS LPB initiatives through
outreach and collaboration with National Meteorological Services (NMSs) and different local institutions.

· To produce gridded products of daily observational data for climate
model validation.

· To describe past decadal-to-interdecadal variability through proxy
climate reconstructions for the post-1850 period for climate model
validation.

· To summarise decadal-scale variability from instrumental and proxy
climate reconstructions.
