<div>Dear Pekka and Edwin,<br>
<br>
Ashante sana, positive leads, exactly what this list is good at.<br>
<br>
We have a large interdisciplinary research project at the
University of Glasgow (<a href="http://livestocklivelihoodsandhealth.org/" target="_blank">Livestock,
Livelihoods and Health</a>) studying Zoonoses in Northern
Tanzania and one of our researchers wishes to create some GIS
tools for predictive disease risk mapping.<br>
<br>
We will certainly check out the Africlim data, especially the
original sources for the raw data. I reckon 1 arc second is
around 30m at the equator which is a compatible resolution to the
Land Cover and DTM data we propose to use. Having access to raw
times series climate data from TMA would allow us to undertake
some modelling for our risk mapping proposals in combination with
the zoonoses data we are collecting through our extensive
fieldwork programme.<br>
<br>

Mike<span class=""><br>

<div>For raster datasets, have you looked at
Africlim dataset by University of York? It
covers the whole Africa at 1 arc-second
resolution.<br clear="none">
</div>
<div>It includes monthly grids of
temperature and rainfall, and derived
bioclimatic summary variables such as
moisture indices and dry season length.
There are both baseline grids (current
conditions) and projected grids for future
conditions under different climate
scenarios (RCPs). <br clear="none">

I know from published reports that the

In particular can anyone supply

1. Name and GPS Location of all

4. Raster data at resolutions better
