Global LST

An hourly, global dataset of Land Surface Temperatures (LST), covering a period of 31 years (1979-2009), derived merging the NCEP/CFSR LST and the HIRS LST retrievals. The combination of the two data sets has been carried out through an uncertainty analysis that assured the final hàng hóa to be consistent with the HIRS data. The data are available at 0.5 degrees spatial resolution & 1 hour temporal resolution.

Bias-Corrected và Downscaled Future Climate Global Meterological Forcing Data: 1948-2099

A global 150-yr (1948-2099) dataset of meteorological forcings derived by bias correcting & downscaling 20th century (scenario 20C3M) & 21st century future climate projections (scenario SRES A2) from the NCAR PCM climate model. The dataset is bias-corrected & downscaled using the newly developed equidistant quantile matching method (Li et al., 2010) which better represents changes in the full distribution (not just the mean change). In addition lớn precipitation & temperature, radiation, humidity, pressure và windspeed are also downscaled. The downsclaing is based on the observational based global forcing dataset of Sheffield et al. (2006) listed above. Available at 1.0-degree spatial resolution and 3-hourly temporal resolution.

High resolution daily meteorological data for northern/west/east Africa

A
10km,
daily meteorological
dataset for
west/east Africa
has
been
developed for 1979‐2008.
The
dataset
is
based
on
the NCEP‐NCAR
reanalysis (NNR)
merged with the University
of
East Anglia Climate Research Unit (CRU) monthly
gridded temperature sản phẩm and
the
NASA
Langley
Surface
Radiation
Budget (SRB)
product.
Downscaling in space is
carried
out with
account
for
changes
in
elevation.
The
CRU product
has
been
evaluated for
temporal inconsistencies that are attributable
to
changes
in
contributing
gauges and
simple
adjustments are carried out
to
remove step
changes. Adjustments are made to
ensure consistency
among variables,
such
as
between downward
longwave
and
humidity/temperature,
and between
temperature
and humidity
to
maintain relative humidity.
Empirical
adjustments to
downward short and
longwave surface fluxes are made to
achieve consistency with
precipitation.
The
dataset
has
been
evaluated
against
observations
from the
US
National
Climatic
Data Center
(NCDC) Global
Summary
of the Day (GSOD) station database,
for
a
range of statistics
at
annual to
daily
time
scale,
including
extremes.
A
method for assimilating
station data
into the gridded dataset was
developed & tested,
and
was
used
to merge available station
data
into
the
full
1979‐2008 gridded
dataset.
Value‐added
products
such
as
annual,
monthly
and
daily
statistics,
extreme
values
and
potential evaporation
were
calculated
from
the
dataset.

High resolution evapotranspiration data from remote sensing for Mexico

Evapotranspiration (ET) data have been generated for Mexico using aremote-sensing based Penman-Monteith approach. Inputs are derivedfrom the ISCCP dataset which is downscaled from 2.5deg lớn 0.125degusing statistical relationships with the NARR. Vegetation distributionand LAI are taken from AVHRR databases. Canopy resistance is based onminimum values for each vegetation type & is modified by LAI andnear surface humidity & minimum temperatures. Soil evaporation isalso calculated.

Ensemble Meteorological Forcing Dataset for the Southeast U.S.

A daily atmospheric forcing dataset over the Southeast U.S. Generated from the seasonal hydrologic ensemble prediction system. The forcing variables are: precipitation, daily maximum temperature and daily minimum temperature, average wind speed. This dataset contains 6-month forcing starting from the beginning of each month from 1981 khổng lồ 1999. Two types of forcing are included: the CFS-based & the ESP-based. Both of them are used for seasonal hydrological predictions, but their forecast skills are different.
