Hello Sir, thank you for the informative tutorial. I am doing the same analysis for my school purposes, and I do not know how to access that data so I can then follow your analysis instructions. Would you help me to understand how can I access that data and arrange them in the right way? Thank you in advance.

Hello Thanks for the great explanation How do we calculate the Palmer drought index?
@geo-95784 жыл бұрын
Thank you for your comment. The Palmer Drought Severity Index (PDSI), is indicator to quantify the long-term drought conditions, for an area at a certain time. pdsi(P, PE, AWC = 100, start = NULL, end = NULL, cal_start = NULL, cal_end = NULL, sc = TRUE) P Monthly precipitation series without NA [mm]. Can be a time series. PE Monthly potential evapotranspiration corresponding to the precipitation series. Can be calculated by the Penman-Monteith or the Thonthwate equation [mm]. AWC Available soil water capacity of the soil layer [mm]. Default 100 mm. start Integer. Start year of the PDSI to be calculate default 1. end Integer. End year of the PDSI to be calculate. cal_start Integer. Start year of the calibrate period. Default is start year. cal_end Integer. End year of the calibrate period. Default is end year. sc Bool. Should use the self-calibrating procedure to calculate the climatical coefficient (K2 and duration coefficients). If I have got data I will show you how we can calculate the pdsi

Hello! Thank you for the video. I am having an issue with my monthly data containing NAs and your "na.value=NA" is not working. Do you have any advise please? Thank you
@geo-95785 жыл бұрын
Nic sorry i very late for the replay i was too busy by filed project any way thanks for your question the problem might be in preparing the data to feed in to the software so leave blank all the NAs in the excel it will be changed in to NA while you call the data in to the R software and you can perform the analysis

thanks for your video.. its very helpful.. I have a question i want to calculate monthly ,seasonal, and yearly precipitation anomaly index. but i dont have daily data... what will i do? Because i don't have any daily data so i cant perform RAI?????? plss give me some suggestions .. I look forward to your suggestions.. thank you very much
@geo-95783 жыл бұрын
I think if you have monthly rainfall you can perform, otherwise you have to collect daily point data from national metrological station.

Hello. Do you have some r codes and datas in R studio for Hidrological modelling? I need codes to load some graphs for making presentation about some data made in R studio. Please help. I have been searching a lot on google and youtube but cant find. I have to make ppt about Hidrological modelling in R so I need r codes and data, if you could recommend me some links I will be grateful.
