Things TODO/read/learn... @ Jan 2019

How to run the BOLAM/MOLOCH models with ERA5 data (on model levels)

Yet another tutorial on how to install WRF

Immagine
Several tutorials on how to install WRF are available online.
Basically the common root is the Official Tutorial from mmm.ucar.
Some other noticeable websites are:
WRF on Ubuntu server 16.04again WRF on Ubuntu server 16.04WRF on CENTOsWRF on Archlinux (with some nice ncl examples)WRF on a generic Linux machineWRF Forum (section Installation)etcetc... Among the several tutorials you find online I'd like to add another (useless?) guide (or script) I used to automate the compilation of the WRF/WPS systems, with some special notes.

It is definitely a non-exhaustive script and it might have some (hopefully non-destructive errors), so.... 
>>>use at your own risk<<<

The prerequisites are:
the netcdf libray (version 4.x) successfully compiled and installed (here in /usr/local)gcc, gfortran (version 5.4.0 or higher) #!/bin/bash # It is supposed that you have the following sources files in $SRCDIR # ARWpost_V3.tar.gz mpich-3.0.4.tar.gz WRFV3.9.1.1.TAR.gz …

Downscaling ERA-5 reanalysis data for coastal climate applications (and evaluation of uncertainty of coastal data)

Immagine
Here's the abstract and the link to the oral presentation I gave this morning at the 5th International Conference on Reanalysys held in Rome, 13-17 November 2017 in the outstanding venue of Angelicum University located in the very centre of Rome.

Downscaling ERA-5 reanalysis data for coastal climate applications (and evaluation of uncertainty of coastal data): The management of coastal zones requires precise data concerning past wind/wave regimes and future climate trends. Many studies have been based on low resolution reanalysis data that cannot allow a detailed description of the variability induced by local conditions. We present a feasibility study where a simple dynamical downscaling of ERA5 reanalysis data is applied through a cascade of regional atmospheric/wave models. A long-term goal of this study is to identify the long-term trends in the last 30-35 years in order to better understand the effects linked to the impact of climate change along the coast. The methodology app…

Code published via github and zenodo

Today, thanks to my colleague alfcrisci, I found pretty straightforward to connect some of the several (too many??) accounts I have (github, zenodo, orcid) into a comprehensive house to publish and protect the code I developed making it citable. You get this  by following the instructions you find here.

valcap/csv2little_r: First release: this is the first trial...
valcap/regens: First release of regens: this is the second trial...

Hope it will be useful in the future!

How to download, mosaic and resample Modis NDVI data

Immagine
Modis NDVI data are fully described here

Briefly: these data are intended to be the continuation of the well-known NOAA-AVHRR Vegetation Index and are currently used in a wide range of applications.

The following procedure (very basic!!! use at your own risk! no waranty!!) works only in a Linux environment (even if it has been ported on a Windows machine under Cygwin).
Pre-requisities: wget and MRT (Modis Reprojection Tool) that needs to be installed properly (that is MRT's bin directory needs to be added to the environmental variable $PATH)
It consists in three Bash script and one auxiliary file, namely:
wrapper_ModisNDVI.shget.ndvi.shmrt.ndvi.shcustom.env Copy all the files in your workin directory and cd to that directory.

Usage: sh wrapper_ModisNDVI.sh YYYY.MM.DD file_env
where YYYY.MM.DD is the year.month.day of the NDVI time step you're interested in as listed in https://e4ftl01.cr.usgs.gov/MOLT/MOD13Q1.006/ and the file file_env (custom.env) contains several setting…
