DIAGNOSTIC: drought indicator

[PeterBergSMHI]

First simple indicator for calculating meteorological drought by consecutive dry days. Can you please assist with setting up the portal page? The yml file would look something like this: Netcdfs for plotting are here (see instructions at the end): https://drive.google.com/drive/u/1/folders/1tUyXlsT2XY4MfBkD4H8khEsBBBVt6_Cc

Both of the below images are to be plotted as maps, preferrably with a "dry conditions" appeal such as the color range 'YlOrBr' from Colorbrewer (http://colorbrewer2.org/)

Fig. 1: Plot the file CMIP5_bcc-csm1-1-m_day_historical_r1i1p1_T2Ms_pr_1990-1999_drymax.nc

Caption: Longest period of consecutive dry days, defined as days with less than 'Dry day limit'.

Fig. 2:

Plot the file CMIP5_bcc-csm1-1-m_day_historical_r1i1p1_T2Ms_pr_1990-1999_dryfreq.nc

Caption: Number of periods of more than 'Minimum duration limit'.

Thanks! Will add to the portal.

Can you supply images for the netcdf files as well? I'm not sure we will be able to create an interactive map right now.

Two png images are now in the same gdrive folder as before: https://drive.google.com/drive/u/1/folders/1tUyXlsT2XY4MfBkD4H8khEsBBBVt6_Cc

I've integrated this into the portal. Could you have a look?

Looks good! Thanks!
