Dear all,
I am looking for sources of data for precipitation and temperature (mostly) in a daily temporal resolution for Sudan, Ethiopia and Eritrea.
Any help appreciated.
Patrick
Hi Patrick. Well, there are some satellite data that can help you to mount a first approach to your problem. However, it is important to note that this kind of data must further adjustments to be representative of observed meteorological data as precipitation and temperature. Otherwise, meteorological data is still a difficult task to obtain for several countries.
Take a look at the TRMM data here: https://trmm.gsfc.nasa.gov/
Hi Patrick, we have some data sets, especially for the Blue Nile region accessible in our NILE data base at: http://rbis.itt.fh-koeln.de/
If you find something let me know you may need some rights for downloading.

I am particularly interested in the "real" observation station data, NOT in gridded or satellite derived data sets (I should have been mentioned;-)).
Cheers, Patrick
Dear Patrick Laux,
The most trusted sources the requested data have national (state) meteorological agencies of Sudan, Ethiopia and Eritrea. Try to get data from these agencies.

The GHCN-D (ftp://ftp.ncdc.noaa.gov/pub/data/ghcn/daily/) and GSOD (https://data.noaa.gov/dataset/global-surface-summary-of-the-day-gsod) databases, both freely available, definitely contain stations for those countries. Check the GHCN-D first, the data tends to be of a better quality.
For Ethiopia, ask to Wuletawu: https://www.researchgate.net/profile/Wuletawu_Abera
He has the data definitely and I am pretty sure he will share with you
Hi
you can access metadata for Africa here
http://www.hydrosciences.fr/sierem/
we also provide the adresses of the national services to ask for data.
You can also find gridded data sets here
https://www.researchgate.net/project/Monthly-rainfall-gridded-data-set-for-Africa
calculated only from available observed data at each monthly time step, ie no bias from an average reference period
Hi Patrick.
Precipitation data from satellite are listed on the IPWG web site at the following page:
http://ipwg.isac.cnr.it/data/datasets.html

Hi Patrick,
Here are the raster files for global daily perception records from 1981:

Good luck.

Hi patrick, a bit late though.
Some times rain or temperature gauge are not sufficient considering that many interpolation schemes suffer with the reductions of gauges. Satellite or reanalysis data are a good option to complement the point measurements.
However, validation is requiere first to adjustment. Here you will find an option to validate those sources of complementary information

For specific station data from Ethiopia:
You can see all the stations and their start of operations here (some have been running for decades, many stations will offer the data for the years you are looking for - note that the NMA has over 1000 stations collecting data):
http://www.ethiomet.gov.et/stations/information
These stations collect the data you are looking for. Data requests have to be made directly to the NMA, and they charge per data point. In theory, you can request data online here:
http://www.ethiomet.gov.et/data_access/request_form
However, in my experience you need to go to the NMA directly, or have someone go on your behalf. However, before going, determine which stations you are looking for. Once you are in the office, the process is relatively straight forward.
Hi
If you use Precipitation from remote sensing products, you can improve their performance using local raingauges. The merging algorithm described in this work have proved to be successful in reducing the remote sensed field error. In the paper the parameters of the merging are analyzed against the raingauges density so that one defines their value with the features of the local raingauge network and, therefore, one will not need to perform a calibration procedure.

Hi, You can extent the time frame of data that you have and improve its accuracy by merging information. Want to improve the performance of your hydrological model on a scarce data basin?!!
